What is a collapsing margin?

The top and bottom margins of blocks are sometimes combined (collapsed) into a single margin whose size is the largest of the individual margins (or just one of them, if they are equal), a behavior known as margin collapsing. The collapsed margin ends up outside the parent.

How do you handle margin collapse?

Dealing with Collapsed Margins The only way to counteract collapsible margins that occur this way is by inserting something between the elements, for example a border. Otherwise, changing the element’s display status to something that is not block-level would be an option.

Why is margin not collapsing?

Margin collapsing only happens to block-level elements. Other than block-level elements no other elements margin can collapse. Here, we have two

tags that were inline-block

, hence their margin does not collapse. Margin collapsing occurs only when the block elements come in direct contact with each other.

Does margin and padding collapse?

You can think of padding/border as a sort of wall; if it sits between two margins, they can’t collapse, because there’s a wall in the way. The width doesn’t matter, either; even 1px of padding will interfere with margin collapse.

Why are margins collapsing?

Collapsing margins happen when two vertical margins come in contact with one another. If one margin is greater than the other, then that margin overrides the other, leaving one margin.

Does Flexbox collapse margins?

There is no margin collapsing in a flex formatting context. A flex container establishes a new flex formatting context for its contents. This is the same as establishing a block formatting context, except that flex layout is used instead of block layout.

What is negative margin?

The margin is described as negative or clean when the pathologist finds no cancer cells at the edge of the tissue, suggesting that all of the cancer has been removed.

Why margin-right is not working?

You cannot see the effect of margin-right because the ‘width’ property of div causes the margin of div to have more than 10px distance from the right wall of the body. Consequently, it causes the margin-right property not to have any visual effect.

In what circumstances do margins collapse?

Do left and right margins collapse?

Only one type of margin can collapse: Vertical (top and bottom). Margin collapse never applies to horizontal (left and right) margins. In other words, when two elements are next to each other on a page (top/bottom), one of the elements might lose its vertical margin.

Is it bad to use negative margins?

2 Answers. No; it’s not bad practice, so long as you’re aware of the fact you’re using negative margins, and that this necessarily ‘pulls’/’moves’ elements from their otherwise-‘normal’ position.

When do two margins collapse into a single margin?

Sometimes two margins collapse into a single margin. Top and bottom margins of elements are sometimes collapsed into a single margin that is equal to the largest of the two margins. This does not happen on left and right margins!

How are top and bottom margins collapsed in CSS?

Top and bottom margins of elements are sometimes collapsed into a single margin that is equal to the largest of the two margins. This does not happen on left and right margins! Only top and bottom margins! In the example above, the element has a bottom margin of 50px and the element has a top margin set to 20px.

Can a border or padding stop margin collapse?

When does the margin of a child element collapse?

That’s a good thought, but what ends up happening is that one continues to get used and one is collapsed. It’s sort of like one swallowed the other, though we’re not sure which one gets swallowed. Collapsing margins also occur when the margin of a child element crosses the margin of its parent.
