What is responsive web design?

Today, the emergence of a large number of different mobile devices with which Internet users access websites has led to the question of when creating websites: how can you develop a website design so that the website displays well on both mobile devices and PC? The task of correctly displaying sites on devices with different screen resolutions is set by adaptive web design. What is it?

Responsive web design is based on the so-called “rubber” principle: the dimensions of the website design elements are proportionally changed, depending on the size of the browser window in which the site is viewed. Responsive website design uses a “rubber” layout, as well as “rubber” images.

The “rubber” layout is used in web design very widely. For a very long time, web designers noticed that the proportional resizing of various blocks on the site pages when resizing the browser window makes the site more universal. After all, it is never known in advance on which monitor each visitor will view the site, and the rubber layout allows you to work with the site comfortably on almost any device.

However, only a “rubber” layout can be insufficient now that sites are sometimes viewed on very small screens. Indeed, even if the size of blocks on a page can be reduced even to zero, then it will not work in the same way, for example, with images.

Therefore, adaptive web design suggests using “rubber” images on the site: not only blocks but also images will change when the browser window is reduced in size. The easiest way to solve this problem is to use the CSS image property {max-width: 100%}. If you apply this property to an image placed in a block, the image will change proportionally with the change in the block itself.

Another way to create “rubber” images is to issue images of the right size from the server at the request of the browser, based on what the current screen resolution is. There are several variations of this method in which Javascript, PHP can be used. CSS3 Media Queries can also be used for responsive web design.

Using the Media Queries rule set in CSS3,

you can set the desired “behavior” of a site when viewing it on different screens. So, for example, if a site is viewed on a widescreen monitor with a higher resolution, then, in this case, the layout may be the most “expanded”: large images arranged in a horizontal row, headers, descriptions. If the screen is smaller and narrower, then the layout may change: pictures are reduced, their relative position from horizontal becomes vertical, titles and descriptions are removed.

At the moment, visitors can access sites from home computers, and from laptops or netbooks, and from tablets, and from mobile phones, and even from e-books, TVs or HD players. That is why it has become important to provide all visitors, regardless of which devices they use, with the opportunity to comfortably browse the site.
