CSS: Colors

Coloring a section of text is a common way to get a user's attention on a page. Various advertising banners are constantly trying to tell us about an incredible discount, or an offer that ends today. In the same way, highlighting can indicate important information that must be read.

Using CSS, you can set the color of the text for the whole page or for a small area. This is determined by the selector you choose. The color itself is set using the property color, the value of which is, naturally, a color.

In this lesson, the color will be written in HEX format, where #ffffff means white and #000000 means black. For convenience, there'll be a link to a portal at the end of the lesson, where you can select any color and get its value in HEX format. We'll talk more about color models in CSS in a future lesson.

Create a paragraph and color one word in it. To do this, let's wrap it in a <span> string tag and give it a class, which we'll use to select the CSS element:

<p><span class="info">Attention!</span> Important information</p>
.info {
  color: #5263f3;

Attention! Important information

If you want to set the text color for an entire page, you can use the body selector. The color property is inherited, so the color will be set for all text elements:

body {
  color: #333333;


In the editor, add a <span> element with the class set to violet, and set its color to #9400d3. Use the <style> tag to include styles.

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.
