Why is my margin top not working?

This issue is known as Margin Collapse and happens sometimes between top and bottom margins on block elements. That’s why the margin doesn’t work on the p tag. And on the a tag the margin doesn’t work because it’s an inline element. You may need to change its display property to inline-block or block .

Is it better to use padding or margin?

With this in mind, a good rule of thumb is to use margin when you want to space an element in relationship to other elements on the wall, and padding when you’re adjusting the appearance of the element itself. Margin won’t change the size of the element, but padding will make the element bigger1.

Does padding and margin 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 is padding important?

The primary use of padding with classical ciphers is to prevent the cryptanalyst from using that predictability to find known plaintext that aids in breaking the encryption. Random length padding also prevents an attacker from knowing the exact length of the plaintext message.

When can we use margin auto?

When you have specified a width on the object that you have applied margin: 0 auto to, the object will sit centrally within it’s parent container. Specifying auto as the second parameter basically tells the browser to automatically determine the left and right margins itself, which it does by setting them equally.

How do I get rid of margin collapsing?

Using a padding or border will prevent collapse only in the latter case. Also, any value of overflow different from its default ( visible ) applied to the parent will prevent collapse. Thus, both overflow: auto and overflow: hidden will have the same effect.

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.
