Having a positioning of absolute and left set to 100%, the child element extends beyond its parent container

Question

Having a positioning of absolute and left set to 100%, the child element extends beyond its parent container

I am experiencing a challenge with my HTML elements, specifically a parent container div and a child div. When I apply the CSS property left: 100% to the child div, it extends beyond the boundaries of the parent div. While using right: 0 or CALC can solve the issue, I am determined to achieve this using only left: 100% without relying on Javascript. Is there a solution to accomplish this?

.parent{
  border: 1px solid #000;
  height: 500px;
  position: relative;
  width: 500px;
}
.child{
  background: #FF0;
  height: 100px;
  left: 100%;
  position: absolute;
  width: 100px;
}

Answer №1

The correct behavior in this scenario is to use the right: 0 property. Setting left:100% will push the child element 100% of the parent's width to the right, which may not be ideal in a fluid layout. Using a negative margin or adding transform: translateX(-100%) to the child may also achieve the desired effect, but it is not recommended in all cases.

Answer №2

One way to achieve this layout is by using a negative margin on the child element within a parent with a fixed width:

.container{
  border: 1px solid #000;
  height: 500px;
  position: relative;
  width: 500px;
}
.element{
  background: #FF0;
  height: 100px;
  left: 100%;
  position: absolute;
  width: 100px;
  margin-left: -100px;
}

If you're looking for another approach, floats could also be an option. While I'm not sure of your end goal, here's an example of how you could implement it:

.container {
  border: 1px solid #000;
  height: 500px;
  width: 500px;
}
.box {
  background: #FF0;
  height: 100px;
  width: 100px;
  float: right;
}

<div class="container">
  <div class="box"></div>
</div>

By setting left:100%, you ensure that the initial border of your child element is positioned right at the edge of its container

If you want the yellow box to be aligned to the right, you have a couple of options to achieve this:

.parent{
  border: 1px solid #000;
  height: 500px;
  position: relative;
  width: 500px;
}
.child{
  background: #FF0;
  height: 100px;
  left: calc(100% - 100px);
  position: absolute;
  width: 100px;

}

.child{
  background: #FF0;
  height: 100px;
  right: 0;
  position: absolute;
  width: 100px;

}
