Media Queries and Responsive Design
With the vast variety of devices and screen sizes today, creating websites
that look great on all of them is essential. Responsive design ensures your site adapts fluidly to
different screen widths, orientations, and resolutions. The key to this
adaptability lies in CSS Media Queries.
What Are Media Queries?
Media queries allow you to apply different CSS
rules based on the characteristics of the user’s device or viewport. This means
you can change the layout, font size, colors, and more depending on whether
someone is using a phone, tablet, desktop, or even printing the page.
Basic Syntax
@media (condition) {
/* CSS rules here */
}
For example:
@media (
max-width:
600px) {
body {
background-color: lightblue;
}
}
This changes the body’s background color to
light blue when the screen width is 600px or less.

Responsive Design Techniques
·
Fluid Grids: Use relative units like percentages or fr
in grids instead of fixed pixels.
·
Flexible Images: Make images scale with max-width set to
100%.
·
Breakpoints: Set media queries at specific screen widths
to adjust layout and typography.
·
Mobile-First Approach: Write styles for small screens
first, then add media queries for larger screens.
Example: Responsive Layout
.container {
display: flex;
flex-direction: row;
}
@media (
max-width:
768px) {
.container {
flex-direction: column;
}
}
This switches a horizontal layout to a
vertical one on tablets and smaller devices.
