CSS Media Queries Basics

CSS

"Learning CSS is like solving a puzzle—except if one piece is out of place, your entire website ends up looking like a closet hit by a tornado!"

Make Your Website Look Good Everywhere! 

Ever visited a website on your phone and thought, “Why does this look like a squished pancake?” Well, my friend, that’s where CSS Media Queries come in to save the day! 

Media Queries allow your website to adapt to different screen sizes—so it looks great whether you're on a giant 4K monitor or a tiny phone screen. No more zooming in and out like a detective trying to read tiny text! 

Let’s dive into the magic of Media Queries and how they can make your website responsive! 

What is a Media Query?

A Media Query is a CSS feature that applies styles based on screen size, resolution, or even device orientation! Think of it as giving your website a wardrobe change depending on where it’s being viewed. 

Here’s a simple example:

@media (max-width: 768px) {
  body {
    background-color: lightblue;
  }
}

If the screen width is 768px or smaller, the background turns light blue!

Basic Syntax of Media Queries

A media query follows this format:

@media (condition) {
  /* CSS rules here */
}

You can specify conditions like:

• max-width (for smaller screens)
• min-width (for larger screens)
• orientation (portrait or landscape)
• resolution (for high-DPI screens)

Example:

@media (min-width: 1024px) {
  body {
    font-size: 18px;
  }
}

If the screen width is 1024px or larger, the font size increases!

Common Media Query Breakpoints

Here are some standard breakpoints for responsive design:

/* Phones */
@media (max-width: 600px) {...}

/* Tablets */
@media (min-width: 601px) and (max-width: 1024px) {...}

/* Desktops */
@media (min-width: 1025px) {...}

These ensure your website adjusts smoothly across devices! 

Combining Multiple Conditions

Want to style based on both width and orientation? No problem!

@media (max-width: 768px) and (orientation: portrait) {
  body {
    background-color: pink;
  }
}

Now, if the screen is 768px or smaller and in portrait mode, the background turns pink! 

Mobile-First vs Desktop-First Approach

There are two ways to approach responsive design:

1. Mobile-First  (Recommended)
   • Start with small screens and add styles for larger ones using min-width.

   body { font-size: 14px; }
   @media (min-width: 1024px) { body { font-size: 18px; } }
   

2. Desktop-First 
   • Start with large screens and adjust for smaller ones using max-width.

   body { font-size: 18px; }
   @media (max-width: 1024px) { body { font-size: 14px; } }
   

Mobile-First is generally better because most users browse on mobile devices!

Conclusion: Why Use Media Queries?
