Websites should be user-friendly and responsive to various devices.

In this article, we’ve selected the best tools and resources to help you adapt your website to a number of gadgets varying in size and operating system. They do not need special knowledge of coding.

Why is testing necessary?

The number and range of portable devices multiplies every day. All of them differ in resolution, size, color reproduction, and dozens of other aspects. Since technology does not stand still, it is necessary to improve and expand the market for devices as well as the web development sphere.

A long time ago, websites used to have a separate version with the ‘m’ prefix in the address bar for mobile gadgets. For example, this happened to vk.com > m.vk.com.

Everything has changed since then. To open the website on a mobile device nowadays, you need to create a specially adapted view that will be adjusted according to all the requirements. Testing is the most important stage that will help to check whether:

  • The design looks nice on mobile devices;
  • Blocks, pictures, icons have shifted;
  • The font is readable;
  • There are any distortions in the logos;
  • The multimedia works correctly;
  • Pop-ups are displayed normally.

The principle of testing is to adapt all performance and visual indicators to certain gadget screens.

Responsive web design itself is an approach to screen orientation and consistency in the design of the Internet pages with the screen settings. There are no defined rules that will be universal for any site and application; everything is calculated and tested individually.

The placement of the text and scrolling of dynamic blocks should be optimal on the maximum number of mobile devices (from tablets to mobile phones).
