¿Cómo se anula el relleno del elemento padre?

How do you override padding of the parent element?

For example, if the parent element has a padding value on the left of 20px, margin-left: -20px on the child element would pull the child element 20px to the left, to align with the left edge of the parent….Everyone wishes they could do this:

1. . child < . parent {
2. padding: 0;
3. }

A CSS pseudo-element is a keyword added to a selector that lets you style a specific part of the selected element(s). For example, ::first-line can be used to change the font of the first line of a paragraph. Note: In contrast to pseudo-elements, pseudo-classes can be used to style an element based on its state.

We can fix this by setting position: relative on the :after pseudo-element. Here’s where things start getting interesting! First, we need to set the stop positions on the gradient of our :before pseudo-element such that they match the bottom and top edges of the parent.

Same as before, our ::after content will be placed just after the p element content but inside the p element itself. We could say that we are creating elements within elements. It’s also important to note that you can’t select the content within pseudo-elements, as you can see in the image below.

We can apply any normal CSS property to the pseudo-element, like color, width, height, etc. These properties will affect only the pseudo-element content and not the original content of the element. Let’s apply some a light grey background color, padding, border and margin to our pseudo-element.

However the key elements above are offset any parent padding with matching negative margins on the child. Then most critical if you want to run the child full-width then set width to auto. (as mentioned in a comment above by schlingel ). Kinda late.But it just takes a bit of math.

Because divs are block-level elements they will automatically expand to the width of their parent. If you put position:relative; on the outer element, the inner element will place itself according to this one. Then a width:auto; on the inner element will be the same as the width of the outer.

The padding-inline-end CSS property defines the logical inline end padding of an element, which maps to a physical padding depending on the element’s writing mode, directionality, and text orientation.

1. Default Case: HTML div is by default fit to content inside it.
2. Using inline-block property: Use display: inline-block property to set a div size according to its content.
3. Using fit-content property in width and height: In this method, we set the width and height property to fit-content value.

For example, with revenue of $750,000 and expenses of $1 million, your negative profit margin equals -$250,000 divided by $750,000, times 100, or -33 percent. This means your net loss for the period equals 33 percent of your sales. For every $1 of sales, you lost 33 cents.

You have a div container and a child element. The child div has a width of 400px but the parent has no width declared. Again, if you add a border, it can happen that the parent div is expanded to 100% while the child div is only 400px. You however may want it to be as wide as the child element – 400px (plus any paddings or margins declared).

This is because the padding is NOT included in the 100px width, this means that it’s actually 120px wide, and your will be 20px from the end of your div. See this jsFiddle for what I mean: jsfiddle.net/YVrWy/1 – Alastair Pitts Nov 28 ’10 at 11:42 Yeah I worked that out when I added it in; the width is irrelevant. – Sam Nov 28 ’10 at 11:45

Your parent is 120px wide – that is 100 width + 20 padding on each side so you need to make your line 120px wide. Here’s the code. Next time note that padding adds up to element width. The problem could come down to which box model you’re using. Are you using IE?

There are a couple of neat CSS tricks for displaying a parent DIV as high as the highest child element and to display the parent DIV only as wide as the child elements occupy inside. It can be quite annoying if you don’t know about this.
