CSS: Responsive Web Design

What are Fluid Grids?

Answer 2

These use relative units like percentages instead of fixed units like pixels, allowing content to resize and reflow based on screen size.

What are Flexible Images?

Answer 3

These are set to resize within their containing elements, ensuring they don’t overflow their containers on smaller screens.

This allows developers to apply different styles based on the characteristics of the device, primarily the viewport width.
@media screen and (min-width: 768px) {
/* Styles for screens at least 768px wide */

@media screen and (aspect-ratio: 16/9) {
/* Styles for screens with a 16:9 aspect ratio */
}

}

Question 14

What are Media Breakpoints?

Answer 14

Media breakpoints are specific points in a website’s design where the layout and content adjust to accommodate different screen sizes. There are some general breakpoints that you can use to target phones, tablets and desktop screens. But it is not wise to try to chase down every single possible screen size for different devices.
/* Styles for screens wider than 768px */
@media screen and (min-width: 768px) {
body {
font-size: 1.125rem;
}
}

Small Devices (smartphones): up to 640px
Medium Devices (tablets): 641px to 1024px
Large Devices (desktops): 1025px and larger

Question 16

What is Mobile First Approach?

Answer 16

The mobile-first approach is a design philosophy and development strategy in responsive web design that prioritizes creating websites for mobile devices before designing for larger screens.
/* Base styles for mobile */
.container {
width: 100%;
padding: 10px;
}

/* Styles for larger screens */
@media screen and (min-width: 768px) {
.container {
width: 750px;
margin: 0 auto;
padding: 20px;
}
}

@media screen and (min-width: 1024px) {
.container {
width: 960px;
}
}
