Expanding a div with content without moving elements below it - html

Question

I have an element on the page which, when it is hovered over, expands and reveals some previously hidden text within it. The problem is that when the element expands, it moves other content below it. I tried to use position:absolute, but it has not achieved the desired effect.
.col {
padding: 20px;
}
.col:hover {
background-color: lightgray;
}
.revealOnHover {
display: none;
/*position: absolute;*/
}
#block1:hover .revealOnHover,
#block2:hover .revealOnHover {
display: block;
}

Answer 1

You're not far off actually. position:absolute is the way to go, but you need a few additional styles to make it work, mainly in order to correctly position it and make it share the background color of its parent.
.col {
padding: 20px;
}
.col:hover {
background-color: lightgray;
}
.revealOnHover {
display: none;
position: absolute;
left: 0;
right: 0;
padding: 10px;
background: inherit;
}
#block1:hover .revealOnHover,
#block2:hover .revealOnHover {
display: block;
}

Answer 2

Add min-height to your row class
Your class becomes
.row {
display: -ms-flexbox;
display: flex;
-ms-flex-wrap: wrap;
flex-wrap: wrap;
margin-right: -15px;
margin-left: -15px;
min-height: 317PX;}

Answer 3

How about adding
.row {
min-height: 20rem
}
This makes sure that they don't move when the divs are being expanded.
