I am centering my element with class "play__circle" using position: absolute; (parent container is set to position:relative;) but when I use transform:scale() then the element doesn’t stay in the center anymore.
Initially the "play__circle" his hidden, but on hover its opacity is set to 1 and scale(0.7).
.container{
width: 200px;
height: 250px;
background-color: rgba(208, 174, 191, 0.8);
position: relative;
padding:5px;
}
.play__circle{
width: 60px;
height: 60px;
background-color: gray;
border-radius: 100%;
position: absolute;
top:50%;
left:50%;
opacity:0;
transform:translate(-50%, -50%);
transition: opacity 300ms ease-in-out, transform 300ms ease-in-out;
}
.container:hover .play__circle{
opacity: 1;
transform:scale(0.7)
}
.content__one{
width: 100%;
height: 50%;
background-color: rgba(205, 184, 86, 0.8);
}
.content__two{
width: 100%;
height: 50%;
background-color: rgba(232, 125, 52, 0.8);
}<div class="container">
<div class="play__circle">
</div>
<div class="content__one">
</div>
<div class="content__two">
</div>
</div>>Solution :
TL;DR. transform properties need to be fully specified when animating
The main concern in your case is that you have transform: translate(-50%, -50%); in your base styling, and only animating it by transform: scale(0.7); on hover. When animating a CSS property with multiple values, you often need to include all custom set values.
That is, when you hover a mouse, CSS will transition only between scale(1) and scale(0.7) values and simply ignore the translate(-50%, -50%) since it’s not specified.
Also, you’d need to specify the transform-origin to top left corner, since you repositioned it by transform and it’s no longer animating from the visual center. See the snippet below.
.container{
width: 200px;
height: 250px;
background-color: rgba(208, 174, 191, 0.8);
position: relative;
padding:5px;
}
.play__circle{
width: 60px;
height: 60px;
background-color: gray;
border-radius: 100%;
position: absolute;
top:50%;
left:50%;
opacity:0;
transform:translate(-50%, -50%);
transform-origin: top left; /* This line is added */
transition: opacity 300ms ease-in-out, transform 300ms ease-in-out;
}
.container:hover .play__circle{
opacity: 1;
transform:scale(0.7) translate(-50%, -50%); /* This line is edited */
}
.content__one{
width: 100%;
height: 50%;
background-color: rgba(205, 184, 86, 0.8);
}
.content__two{
width: 100%;
height: 50%;
background-color: rgba(232, 125, 52, 0.8);
}<div class="container">
<div class="play__circle">
