Extend child div beyond container div

Question

I\'m trying to expand this div across with width of the browser. I\'ve read from here that you can use {position:absolute; left: 0; right:0;} to achieve that a

Answer 1

I had a case where I needed to make a carousel and have it wrap outside of the parent element. You can set the child element to have a width: 100vw and set the parent element to have a max-width of a specific amount of pixels...or a calculated amount. With this setup our child component extends itself beyond the parent. JSFiddle

    .parent {
     // our parent container has 20px margins on each side so we set its max width accordingly
      max-width: calc(100vw - 20px)
    }

    .child {
      // set the child to wrap the entire viewport width. Account for any margins from the parent and offset them with a negative margin
      width: 100vw;
      transform: translateX(-20px);
    }

Answer 2

Parent to position:static, child to position:absolute or

Parent to position:relative, child to position:fixed (with the fixed, never moving downside)

Your left: 0; right:0; works with both of these solutions, just note that your child div will draw on top of any divs below it in code, no matter what the div's display property is set to. You will either have to add a padding-top value to the next div to compensate (simple example in jsfiddle), or another div underneath that has the same height behavior as the child (a much more elaborate example in codepen), which is probably not ideal, but works in simple html/css.

Answer 3

I can think of five ways to potentially accomplish your goal:

1. Use negative margins on the inner element to move it outside of the parent

2. Use Javascript to move the inner element outside of the parent.

3. Change the source code and move the inner element outside of the parent.

4. Use position: fixed on the inner element. This will allow the inner element to break out but has the down side that the element will be fixed at the given position (never moving).

5. Remove the position: relative; from the parent element or give the parent element a position: static

Answer 4

You can try adding overflow:visible to the parent div, then making the child wider than the parent.
