Tailwindcss best practices for responsive design

Programing Coderfunda July 01, 2025 Tailwind-Css No comments

Tailwind CSS provides powerful utilities for responsive design out of the box. To use it effectively and maintain clean, scalable code, here are best practices for responsive design in Tailwind CSS:

✅ 1. Mobile-First Approach

Tailwind uses a mobile-first breakpoint system. That means:

Base styles apply to all screen sizes.
Use responsive prefixes (like sm:, md:, etc.) to override styles at larger breakpoints.

<div class="text-base md:text-lg lg:text-xl">Responsive Text</div>

✅ 2. Use Tailwind's Breakpoints Strategically

Tailwind’s default breakpoints are:

sm: 640px
md: 768px
lg: 1024px
xl: 1280px
2xl: 1536px

You don’t have to use all of them. Apply breakpoints only where design truly changes to avoid clutter.

✅ 3. Consolidate Classes with Responsive Variants

Avoid repeating the same base styles for each breakpoint. Stack only what’s needed.

<!-- Bad -->
<div class="text-sm sm:text-sm md:text-base lg:text-lg xl:text-xl">
<!-- Good -->
<div class="text-sm md:text-base lg:text-lg xl:text-xl">

✅ 4. Use Flex/Grid Utilities for Layout

Take advantage of Tailwind's flex, grid, and gap utilities for layout instead of writing custom CSS.

<div class="grid grid-cols-1 md:grid-cols-2 gap-4">

✅ 5. Use Utility Components for Reusability

Create reusable components using @apply in your CSS or extract components in your framework (React, Vue, etc.).

/* styles.css */
.btn {
  @apply px-4 py-2 bg-blue-500 text-white rounded hover:bg-blue-600;
}

✅ 6. Avoid Overusing Inline Responsive Classes

When components become complex, consider extracting styles to classes with @apply, or move to JSX/component-based logic.

<!-- Instead of -->
<div class="p-2 sm:p-4 md:p-6 lg:p-8 xl:p-10">...</div>

<!-- Use a component with logic or a utility class -->
<div class="responsive-padding">...</div>

✅ **7. Use `container` with `max-w-*` for Centered Layouts**

The container class + mx-auto + max-w-* gives you responsive content width and alignment.

<div class="container mx-auto px-4 max-w-7xl">

✅ 8. Test on Real Devices or Emulators

Don’t rely solely on browser resizing. Use Chrome DevTools or tools like Responsively App to test your layout on real device resolutions.

✅ 9. Use Plugins for Custom Breakpoints if Needed

If your project has custom design specs, you can extend Tailwind's default breakpoints in tailwind.config.js.

theme: {
  extend: {
    screens: {
      'xs': '480px',
      '3xl': '1600px',
    }
  }
}

✅ 10. Use Logical Class Ordering

Organize your class names logically for readability:

Layout → Box Model → Typography → Visuals → Responsive

Example:

<div class="flex items-center justify-between p-4 bg-gray-100 text-sm md:text-base">

Tailwind CSS Tutorial (Beginner to Master)

Programing Coderfunda July 01, 2025 Tailwind-Css No comments

Here's a simple and complete Tailwind CSS tutorial designed for students and beginners, progressing step-by-step from beginner to master level. This guide is easy to follow, practical, and helps build real-world UI skills.

🎯 Tailwind CSS Tutorial (Beginner to Master)

Simple & Best Way for Students

✅ 1. What is Tailwind CSS?

Tailwind CSS is a utility-first CSS framework for building custom designs without writing traditional CSS. You use pre-built classes like bg-blue-500, text-center, p-4, etc.

✅ 2. Why Use Tailwind CSS?

No need to write custom CSS
Faster development
Fully responsive
Easily customizable
Works with all frontend frameworks (HTML, React, Vue, etc.)

✅ 3. How to Install Tailwind CSS (2 Easy Ways)

🔹 Option 1: Use CDN (For Beginners)

Paste this in your HTML file <head>:

<link href="https://cdn.jsdelivr.net/npm/tailwindcss@2.2.19/dist/tailwind.min.css" rel="stylesheet">

✅ Good for practice
❌ Not recommended for production

🔹 Option 2: Install with NPM (Professional Setup)

npm init -y
npm install -D tailwindcss
npx tailwindcss init

Create tailwind.config.js and setup input.css:

/* input.css */
@tailwind base;
@tailwind components;
@tailwind utilities;

Build CSS:

npx tailwindcss -i ./input.css -o ./output.css --watch

Then link output.css in HTML.

✅ 4. Tailwind CSS Structure (Basics)

<div class="p-4 bg-blue-500 text-white text-center rounded-lg">
  Hello Tailwind!
</div>

🔹 Common Utilities:

Utility	Example	Meaning
Padding	`p-4`	padding: 1rem
Background	`bg-red-500`	red background
Text color	`text-white`	white text
Text align	`text-center`	center text
Rounded corner	`rounded-lg`	border-radius

✅ 5. Responsive Design

Tailwind is mobile-first. Use breakpoints:

<div class="text-sm md:text-lg lg:text-xl">Responsive text</div>

✅ 6. Layout with Flex & Grid

🔹 Flexbox:

<div class="flex justify-between items-center">
  <span>Left</span>
  <span>Right</span>
</div>

🔹 Grid:

<div class="grid grid-cols-2 gap-4">
  <div>Box 1</div>
  <div>Box 2</div>
</div>

✅ 7. Components Examples

🔹 Button

<button class="px-4 py-2 bg-green-500 text-white rounded hover:bg-green-600">
  Click Me
</button>

🔹 Card

<div class="max-w-sm rounded overflow-hidden shadow-lg p-4 bg-white">
  <h2 class="text-xl font-bold mb-2">Card Title</h2>
  <p class="text-gray-700">This is a card description.</p>
</div>

✅ 8. Master Level Tips

🔹 Use `@apply` to create reusable classes:

/* styles.css */
.btn {
  @apply px-4 py-2 bg-blue-600 text-white rounded hover:bg-blue-700;
}

🔹 Customize `tailwind.config.js`

theme: {
  extend: {
    colors: {
      brand: '#1e40af',
    }
  }
}

✅ 9. Project Ideas for Practice

Project	Skills Practiced
Portfolio Site	Layout, responsive design
Login Form	Form styling
Blog Layout	Grid, typography
E-commerce UI	Cards, buttons, filters

✅ 10. Resources for Learning

🌐 Tailwind Docs
📺 YouTube Channels: Traversy Media, The Net Ninja, Code with Harry
💡 Use Tailwind Play to experiment online

✅ Summary: Learning Path

Level	Learn
Beginner	Basic classes, text, padding, layout

pyspark XPath Query Returns Lists Omitting Missing Values Instead of Including None

Programing Coderfunda September 20, 2024 No comments

I have a PySpark DataFrame with a column containing XML strings, and I'm using XPath queries with absolute paths to extract data from these XML strings. However, I've noticed that the XPath queries return lists that omit values if they are not present, rather than including None in their place. I would like to keep the length of the lists consistent, filling in None where data is missing.

Here is the sample data and code I'm working with:
data = [
(1, """

Lion

Apple

Banana

Tiger

Cranberry

"""),
(2, """

Lion

Apple

Tiger

Banana

Zebra

""")

df = spark.createDataFrame(data, ["id", "xml_string"])

What the XPath queries return:

For data column:
(1, ["Apple","Banana","Cranberry"], ["Lion","Tiger"])
(2, ["Apple","Banana"], ["Lion","Tiger","Zebra"])
What I want:

For data column:
(1, ["Apple","Banana","Cranberry"], ["Lion", None, "Tiger"])
(2, ["Apple","Banana", None], ["Lion","Tiger","Zebra"])

How can I adjust my XPath queries?
root/level1/level2/level3/level4/data

root/level1/level2/level3/data2

SQL REPL from within Python/Sqlalchemy/Psychopg2

Programing Coderfunda September 20, 2024 No comments

It's helpful to have a DB CLI available for writing quick raw SQL queries. Suppose that the 1 minute it takes to remind myself how to type the correct version of psql postgresql://username@localhost:5432 is simply too long.

Is there any convenience method like engine.interactive() that just drops you into a CLI in the current database, similar to breakpoint() dropping you into a PDB? One thing I considered was
subprocess.run(['psql', engine.url])

But that doesn't work since psql doesn't accept the +psycopg2: bit of the sqlalchemy connection string.
$ psql postgresql+psycopg2://postgres:dev@localhost:5432/
psql: error: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: FATAL: role "root" does not exist

$ psql postgresql://postgres:dev@localhost:5432/
psql (16.4 (Debian 16.4-1.pgdg120+1))
Type "help" for help.

postgres=#

I can slice it off myself and this works:
def enter_cli(engine):
url = engine.url.set(drivername=url.drivername.split("+")[0])
connection_string = url.render_as_string(hide_password=False)
subprocess.run(["psql", connection_string])

But that seems likely to be non-portable, as I'm hardcoding the CLI and the specific type of connection string. (e.g. it looks like pgcli wants postgres:// and doesn't accept postgresql://.) The other approach would be writing a python-based CLI, but with the naive approach you lose a lot of tab-completion and similar features. Is there a portable way to do this?

AdminJS not overriding default dashboard with custom React component

Programing Coderfunda September 19, 2024 No comments

So, I just started with adminjs and have been trying to override the default dashboard with my own custom component. I read the documentation and I don't think I am doing anything wrong? yet it still wont load the component. I started with a basic component to see whether it works or not.
It's being initialized but its not overriding the default dashboard.
AdminJS initialized with dashboard: { component: 'Dashboard' }

Code is provided below
Dashboard.jsx:
import React from 'react';
import { Box } from '@adminjs/design-system';
import { useTranslation } from 'adminjs';

const Dashboard = () => {
const { translateMessage } = useTranslation();
console.log('dashboard component loading...')
return (

{translateMessage('helloMessage', 'Hello')}

);
};

export default Dashboard;

admin.js:
import AdminJS from 'adminjs';
import { Database, Resource } from '@adminjs/sequelize';
import Customers from './src/models/Customers.js';
import Product from './src/models/Product.js';
import People from './src/models/People.js';
import Companies from './src/models/Companies.js';
import Leads from './src/models/Leads.js';
import Offers from './src/models/Offers.js';
import { ComponentLoader } from 'adminjs';

const componentLoader = new ComponentLoader();

const Components = {
Dashboard: componentLoader.add('Dashboard', './src/components/Dashboard.jsx')
};

AdminJS.registerAdapter({ Database, Resource });

const adminOptions = {
dashboard: {
component: Components.Dashboard
},
componentLoader,
resources: [{
resource: Customers,
options: {
parent: null,
properties: {
id: {
isVisible: { list: false, edit: false, show: false },
},
type: {
position: 1,
availableValues: [
{ value: 'company', label: 'Company' },
{ value: 'person', label: 'Person' },
],
},
name: {
position: 2,
},
email: {
position: 3,
},
phone: {
position: 4,
},
country: {
position: 5,
},
},
},
},
{
resource: People,
options: {
parent: null,
},
},
{
resource: Companies,
options: {
parent: null,
},
},
{
resource: Leads,
options: {
parent: null,
properties: {
type: {
availableValues: [
{ value: 'company', label: 'Company' },
{ value: 'person', label: 'Person' },
],
},
},
},
},
{
resource: Offers,
options: {
parent: null,
},
},
{
resource: Product,
options: {
parent: null,
},
},
],
rootPath: '/admin',
};

export default adminOptions;

server.js:
import AdminJS from 'adminjs'
import AdminJSExpress from '@adminjs/express'
import express from 'express'
import dotenv from 'dotenv'
import sequelize from './src/config/db.js';
import { Database, Resource } from '@adminjs/sequelize';
import adminOptions from './admin.js';

dotenv.config();

const PORT = 3000;

const start = async () => {
const app = express()
AdminJS.registerAdapter({ Database, Resource });
const admin = new AdminJS(adminOptions);
console.log('AdminJS initialized with dashboard:', admin.options.dashboard);

const adminRouter = AdminJSExpress.buildRouter(admin)
app.use(admin.options.rootPath, adminRouter)

app.listen(PORT, async () => {
console.log(`AdminJS started on
http://localhost:${PORT}${admin.options.rootPath}`) />
try {
await sequelize.authenticate();
console.log("database connected successfully")

await sequelize.sync();
console.log("database models synchronized")
}
catch (err) {
console.log("error connecting to database", err)
}
})
}

start()

I tried logging any information regarding it but it seems like it's not loading the component at all?
Any help or suggestions would be appreciated. Thanks!

Fetch PHP is a Lightweight HTTP Library Inspired by JavaScript's fetch()

Programing Coderfunda September 19, 2024 No comments

---

Fetch PHP is a lightweight HTTP library inspired by JavaScript's fetch, bringing simplicity and flexibility to PHP HTTP requests. It uses the Guzzle client behind the scenes, offering synchronous and asynchronous requests with an easy-to-use API

I know that Guzzle is king, and I will use Laravel's HTTP client on most projects. However, the Fetch PHP package is just downright fun when you want a no-frills fetch() function:
$response = fetch('
https://jsonplaceholder.typicode.com/todos/1');">
https://jsonplaceholder.typicode.com/todos/1'); />
// Get the JSON response
$data = $response->json(assoc: true);
print_r($data);
/*
[
"userId" => 1,
"id" => 1,
"title" => "delectus aut autem",
"completed" => false
}
*/

// Get the status text (e.g., "OK")
echo $response->statusText();

Available Response Methods

*
json(bool $assoc = true): Decodes the response body as JSON. If $assoc is true, it returns an associative array. If false, it returns an object.

*
text(): Returns the response body as plain text.

*
blob(): Returns the response body as a PHP stream resource (like a "blob").

*
arrayBuffer(): Returns the response body as a binary string.

*
statusText(): Returns the HTTP status text (e.g., "OK" for 200).

*
ok(): Returns true if the status code is between 200-299.

*
isInformational(), isRedirection(), isClientError(), isServerError(): Helpers to check status ranges.

The asynchronous requests use the fetchAsync() function to can be used as follows:
//
// Asyc requests
//
$promise = fetchAsync('
https://jsonplaceholder.typicode.com/todos/1');">
https://jsonplaceholder.typicode.com/todos/1'); />
$promise->then(function ($response) {
$data = $response->json();
print_r($data);
});

// Wait for the promise to resolve
$promise->wait();

//
// Error handling
//
$promise = fetchAsync('
https://nonexistent-url.com'); />
$promise->then(function ($response) {
// handle success
}, function ($exception) {
// handle failure
echo "Request failed: " . $exception->getMessage();
});

You can also pass Guzzle options to the fetch() and fetchAsync() functions for any advanced Guzzle features you'll need. You can learn more about this package, get full installation instructions, and view the source code on GitHub.

window.location.replace() is not working

Programing Coderfunda September 18, 2024 No comments

just wanna ask why does window.location.replace is not working in my page. I've been working on it for weeks. It works fine on my other pages, although those pages have DevExpress components, but in this particular page where I am only using normal html and asp tags and components it is not working. It seems to be refreshing only and not redirecting. Here is my code for the button:

My first Laravel package - Translation checker for Laravel

Programing Coderfunda September 18, 2024 No comments

Hey everyone!

I have created my first Laravel package, Translation Checker! It's designed to simplify the process of managing translations in your lang folders, so you no longer need to manually add new translations whenever you add a new translation string.

I built this into a package because it solved a personal need, and gave me a chance to try parsing PHP, and now, I decided to open-source.
Check it out on GitHub: Translation Checker

If you're working with multi/bi-lingual applications, whether open-source or closed-source—let me know! I’m eager for it to be tested in more real-life cases and make it work with different workflows other than my own.

Any feedback is appreciated :) submitted by /u/cawex

Validate Console Command Input With the Command Validator Package

Programing Coderfunda September 18, 2024 No comments

The Command Validator package by Andrea Marco Sartori makes validating the input of console commands a cinch using Laravel's beloved Validator. All the Laravel Validator rules you know and love work with this package, along with any custom validation rules.

This package integrates with your application's console commands using the provided ValidatesInput trait, which includes an abstract rules() method. The command signature looks like the following:
namespace App\Console\Commands;

use Illuminate\Console\Command;
use Cerbero\CommandValidator\ValidatesInput;

class SampleCommand extends Command
{
use ValidatesInput;

protected $signature = 'app:sample {--start-date=}';

// ...

public function rules(): array
{
return ['start-date' => 'date_format:Y-m-d'];
}
}

I find it really neat that you can use a closure-based custom validation rule directly in your console command with command-specific business logic:

public function rules(): array
{
return [
'start-date' => [
'date_format:Y-m-d',
function (string $attribute, mixed $value, Closure $fail) {
$date = Carbon::parse($value);
$startOfYear = Carbon::now()->startOfYear();

if ($date->lessThan($startOfYear)) {
$fail("The {$attribute} must be a date from {$startOfYear->format('Y-m-d')} or later.");
}
}
],
];
}

When validation passes, you know you're working with valid input, and your handle() method can stay clean from manual validation checks.

Another neat use-case using the built-in validation rules is validating that an input exists in the database automatically with the exists rule:
public function rules(): array
{
return ['user-id' => 'exists:users,id'];
}

Sure, you could easily query a user and conditionally return an error, but I think it's neat that you can validate it using exists automatically and give back a default error message when a record doesn't exist.

You can use this package in your project by installing it via Composer:
composer require cerbero/command-validator

using type parameters in generic constraints in TypeScript

Programing Coderfunda September 18, 2024 No comments

I have the following ts code in many places:

(note here's a typescript playground with the example)
let filtered = items.filter(item =>
item.title.toLowerCase().includes(search.toLowerCase()) ||
item.name.toLowerCase().includes(search.toLowerCase()) ||
item.date.toLowerCase().includes(search.toLowerCase())
);

So I created this function
function filterByKey(items: T[], keys: K[], search: string) {
return items.filter((item) =>
keys.some((key) => item[key].toString().toLowerCase().includes(search.toLowerCase()))
);
}

to call it like this:
let filtered = filterByKey(items, ['title', 'name', 'date'], search));

But I'm getting this error:
Property 'toString' does not exist on type 'T[K]'

I tried like this, but it doesn't seem like a valid syntax
function filterByKey(items: T[], keys: K[], search: string)

how can I tell ts that the properties of items will support .toString()

or how would you handle such a case so taht typescript won't complain?

I checked this ts documentation:
https://www.typescriptlang.org/docs/handbook/2/generics.html#using-type-parameters-in-generic-constraints
