null: Block and line elements
As you get acquainted with many HTML elements, you will notice that their behavior is not always the same: some elements (paragraphs, lists, <pre>, <div>, headings, tables) always start on a new line. They take up the entire width of the screen. Such elements are called block-level elements. They are the basis of HTML layout because they directly affect how elements next to them will be arranged on the page.
In addition to block elements, there are inline elements**. These include links (<a>), tags (<b>, <strong>, <i>, <em>), pictures, and <span>. They do not affect the location of neighboring elements and are designed to provide meaning. Unlike block elements, line elements do not occupy the entire width of the screen, only the space that they need
<p>A paragraph is a block-level element.</p>
<p>It takes up all the space in the width, so each paragraph starts on a new line.</p>
<span>Span is an inline element.</span>
<span>It occupies a width equal to the width of its content, so there is no line break.</span>
A paragraph is a block-level element.
It takes up all the space in the width, so each paragraph starts on a new line.
Span is an inline element. It occupies a width equal to the width of its content, so there is no line break.Instructions
Add two <span> tags with text inside. See how they will be positioned
Tips
Inline elements are often used for style purposes. For example, the
<span>tag is used to wrap a section of text. Then this section is styled using CSSIn most cases, inline elements can be placed inside of block elements, and block elements cannot be placed inside of lowercase elements. The exception is references. Block elements can be placed inside a link. This is allowed in the HTML5 standard
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 links = document.querySelectorAll('span');
5
6 expect(links).to.be.length(2);
7});
