CSS: Margins
Internal indents allowed you to add padding to the block and space between the border of the block and its content. But how do you keep two adjacent blocks from pressing against each other?
To separate the two cards from the example above, you use outer indents. Their principle is the same as the margins, only the direction is different. In terms of properties and their values, it's the same. There are 4 rules and one general one:
margin-topmargin-rightmargin-bottommargin-left
To combine values, use the margin property, which preserves the order in which it's specified:
- top
- right
- bottom
- left
Also, as with margins, there are shorthand versions of these rules for convenience:
- If you specify only one value, it will be used simultaneously for all sides
- If you specify two values, the first will be used for vertical (top and bottom) margin and the second for horizontal (right and left) margin
- If you specify three values, they will be used for top, horizontal and bottom margin
<div class="card">A card with white text on a purple background</div>
<div class="card">A card with white text on a purple background</div>
.card {
margin: 10px 0;
color: #ffffff;
background-color: #673ab7;
}
Instructions
Add <div> to the editor with the class set to margin and set the margins to 20 pixels on all sides. Write the styles in the <style> tag. Use shorthand notation
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 element = query(document, '.margin');
5
6 const style = getComputedStyle(element);
7 expect(style).to.have.property('margin', '20px');
8});
