Why is Responsive Design So important?

Here are a few reasons why CSS responsive web design is important -

  • Device-Independent Rendering

This is the most important advantage of responsive design. With so many kinds of devices in use now, there is no uniform standard of size, shape, or display parameters across devices. This is where responsive design comes into play, as it makes devices optimal in their firmware environments.

  • Usage Experience

A responsive website will lead to a more robust user experience. The number of time a user spends on your site may be a key factor that indicates the quality of the user experience. If they find it difficult to navigate or use your website because they're forced to continuously pinch and center, they'll not be your website. And if your website scales and reacts to the change in screen size, visitors won’t have trouble accessing menu options, links, buttons, or filling out forms. As a result, the user experience will be way better and so they're going to spend significantly more time on your site.

A Mobile-First Approach to Responsive Web Design

The Mobile-first approach means to design the mobile website first and dealing up to the desktop version. There are a variety of reasons why this approach is effective and preferred.

  • A mobile website is more complex to style, so it’s practical and more efficient for the first focus to fix the mobile design.
  • It’s easier to rescale the mobile version than it's to scale down the desktop version.

Setting the Viewport

Pages optimized for a variety of devices must include a meta viewport tag in the document's head. Add the following <meta> tag to all your web pages:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

Responsive Images

Images that can be scaled to fit in size are known as responsive images.

How to Make Image Responsive?

By Using the Width Property

Set the width to 100% to make the image responsive and scale up and down.


Using the Max-Width Property

You can also make the image responsive by using the max-width property. The advantage of this property is that you can never scale up to be larger than the image’s original size.

@media media-type and (media-feature-rule) {

  /* CSS rules go here */
