About the test

The HTML/CSS online test assesses knowledge of HTML and CSS through a series of live coding questions that test the ability to implement and style a user interface. Tasks on this test are executed inside the Google Chrome web browser.

The assessment includes work-sample tasks such as:

  • Defining HTML elements and their attributes, and applying CSS styles to them.
  • Creating forms to group inputs and collect user data.
  • Using responsive web design principles.

A good Web front-end developer or UI/UX developer needs a solid understanding of HTML and CSS in order to create and style web pages and user interfaces that both look good and are easy to navigate.

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
