CSS: Style inheritance
When you use styles in CSS, it often affects not only the element for which the style is specified but also the tags attached to it. Such styles are called inherited styles. The font-size style from the last lesson is inherited - it will apply to all nested tags.
<div style="font-size: 20px;">
The text's font size is 20 pixels.
<p>The nested paragraph will also have a font size of 20 pixels.</p>
</div>
The nested paragraph will also have a font size of 20 pixels.
In addition to the styles that are inherited for all nested tags, CSS has many styles that are unique to the element to which they are applied.
One such property is border, which allows you to set a border around the element. But that same frame won't be copied for every internal element.
<div style="border: 2px solid #000;">
The block will have a border with a width of 2 pixels
<p>And the paragraph will not have its own border. If necessary, it can be set separately</p>
<p style="border: 1px solid #000;">For example, like this</p>
</div>
And the paragraph will not have its own border. If necessary, it can be set separately
For example, like this
Instructions
Add the <div></div> tag to the editor and, using the attributes, set the font size to 20 pixels. Inside the <div> tag, enclose a paragraph with a font size of 10 pixels
Definitions
- Inherited properties
- are properties that are set not only for an element, but for all elements within it, including nested ones
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.

Your exercise will be checked with these tests:
1const { test } = require('tests');
2
3test(({ query, expect }) => {
4 const div = query(document, 'div');
5 const p = query(div, 'p');
6
7 const styleDiv = getComputedStyle(div);
8 expect(styleDiv).to.have.property('font-size', '20px');
9
10 const styleP = getComputedStyle(p);
11 expect(styleP).to.have.property('font-size', '10px');
12});
