HTML: Inserting computer code into HTML
If you have a programming tutorial blog or write articles, then you'll need to demonstrate your code. Every lesson on Code Basics has these blocks:
<p>You can see the markup here</p>
To create a block of code, use the tag <code>, and you can write code in any language there.
// Example code in JavaScript
const square = (num) => {
return num * num;
};
The <code> tag is often used with the <pre> tag to preserve formatting. If the <pre> tag is not used, you have to control line breaks yourself, for example by wrapping each line with a <p> tag.
It's important that all tags inside <code> are be processed by the browser, which is why special characters are used inside. Also, a common solution is to wrap the name of the tag in a separate tag, such as <span>:
<code>
<<span>p</span>>Insert the p tag as plain text <<span>/p</span>>
</code>
Instructions
Add any text to the <code> tag and paste it into the editor. Try different versions of the texts
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
5 const code = query(document, 'code');
6 expect(code).to.be.visible;
7
8});
