CSS: Background

While we've been studying CSS, we've already encountered setting a custom color for text inside a block. But that's not the only option for setting a color - you can set it as the background for the entire block.

Note that the area with the theory and the editor in the lessons are separated from the rest of the site with a white background. This is done not only for easy reading, but also to help your eyes quickly find the area with the main content. To set the background color, we use the property background-color, the value of which is, of course, a color.

You can use hex values for the color:

<div class="card">A card with white text on a purple background</div>
.card {
  color: #ffffff;
  background-color: #673ab7;
A card with white text on a purple background


Add <div> to the editor with the class set to background and set the background color #2196f3. Write styles in the <style> tag

The exercise doesn't pass checking. What to do? 😶

If you've reached a deadlock it's time to ask your question in the «Discussions». How ask a question correctly:

  • Be sure to attach the test output, without it it's almost impossible to figure out what went wrong, even if you show your code. It's complicated for developers to execute code in their heads, but having a mistake before their eyes most probably will be helpful.
In my environment the code works, but not here 🤨

Tests are designed so that they test the solution in different ways and against different data. Often the solution works with one kind of input data but doesn't work with others. Check the «Tests» tab to figure this out, you can find hints at the error output.

My code is different from the teacher's one 🤔

It's fine. 🙆 One task in programming can be solved in many different ways. If your code passed all tests, it complies with the task conditions.

In some rare cases, the solution may be adjusted to the tests, but this can be seen immediately.

I've read the lessons but nothing is clear 🙄

It's hard to make educational materials that will suit everyone. We do our best but there is always something to improve. If you see a material that is not clear to you, describe the problem in “Discussions”. It will be great if you'll write unclear points in the question form. Usually, we need a few days for corrections.

By the way, you can participate in courses improvement. There is a link below to the lessons course code which you can edit right in your browser.
