IE with position absolute element will create horizontal scroll - html

Question

I want to use position: absolute to create a centered element, but it will create a horizontal scrollbar on Internet Explorer 11. Please see the script below. Anyone here knows how to fix this problem?
*Update: I figured out that using overflow:hidden seems to solve this problem somehow. But when there are another one outside of the container, it will be hidden as well.
.container {
width: 80%;
margin: 0 auto;
height: 100vh;
border: 1px solid green;
position: relative;
overflow: hidden; /*This one is not the solution, though*/
}
.content {
width: 80%;
height: 30px;
position: absolute;
top: 50px;
left: 50%;
transform: translate(-50%, 0);
border: 1px solid red;
}
.another-content {
width: 40px;
height: 40px;
border: 1px solid blue;
position: absolute;
bottom: 20px;
right: -20px;
}
<div class="container">
<div class="content"></div>
<div class="another-content"></div>
</div>

Answer 1

You need to add following properties with the position absolute in IE
position: absolute;
top:0;
right: 0;
left: 0;
bottom:0; //specify all including bottom:0

Answer 2

The scrollbar show up in all browsers, not only IE. You can do the following:
The biggest issue is that the left: 50% and width: 80% together are adding to the total width and forcing the horizontal scrollbar to show up in some browsers (e.g. Internet Explorer and MS Edge). You set the width to 80%, so divide the remaining 20% between the left and right border and you'll end up with 10% each. Simply use left: 10% to achieve the same result, but without the side effect of the horizontal scrollbar.
Also when you set the size to 100% and then add border, those borders will be out of the view and cause the scrollbars to show up. This is the same in all browsers. Use box-sizing: border-box to force the browser to include the border in the height and width calculation.
The height: 100vh makes the box height equals to the view port. However, the body has default margins which vary from one browser to another. You can either set those margins to zero body { margin: 0; }, or change the height to height: 100% which is 100% of the container which the body in this case.
Try this:
.container {
width: 100%;
height: 100%;
border: 1px solid green;
position: relative;
box-sizing: border-box;
}
.content {
width: 80%;
height: 30px;
position: absolute;
top: 50px;
left: 10%;
border: 1px solid red;
}
<div class="container">
<div class="content"></div>
</div>

Thanks for your replies. Though they are not direct solution, they helped me a lot to figure out how to solve it.
The cause is as what Racil Hilan said. When I use left:50% and width:80%, the content width will be added up and create a horizontal scroll, which is not ignored by only IE. And my point is to avoid creating that added-up width. Here is my two way to workaround this one.
* {
box-sizing: border-box;
}
.container {
width: 100%;
height: 100vh;
border: 1px solid green;
position: relative;
}
.content {
width: 80%;
height: 30px;
position: absolute;
top: 50px;
left: 0;
right: 0;
border: 1px solid red;
margin: 0 auto;
}
.content-wrapper {
border: 1px solid black;
height: 30px;
position: absolute;
top: 100px;
left: 0;
right: 0;
}
.another-content {
width: 80%;
display: block;
height: 100%;
border: 1px solid red;
margin: 0 auto;
}
<div class="container">
<div class="content"></div>
<div class="content-wrapper">
<div class="another-content"></div>
</div>
</div>
