Overflow hidden not working on hover - html

Question

I have this div and I want to show the title when I hover over title div. The problem is that I get the hover effect even if I hover on the edges of the div. So the div is treated as a square and not as a circle when I hover on it. This works pretty well on Firefox but not on Chrome and Safari.

Note: I do not want to change the aspect ratio of the image. The image should be 100% of the parent height.
HTML
<div class="video_wrap update" video_name="rikthejmna">
<div class="related img_wrap"><img src="http://img.youtube.com/vi/XyzYVpJGRG8/hqdefault.jpg"></div>
<div class="title">rikthejm na</div>
</div>
CSS
.video_wrap {
width: 232px;
height: 232px;
display: inline-block;
border-radius: 116px;
overflow: hidden;
margin: 10px;
position: relative;
z-index: 2;
}
.img_wrap img {height: 100%}
.related {height: 100%;}
.title {
position: relative;
top: -50px;
left: 0px;
background: #fff;
height: 50px;
opacity: .5;
color: #f8008c;
font-size: 12px;
text-align: center;
line-height: 50px;
overflow: hidden;
cursor: default;
transition: all .5s ease-in;
}
.title:hover {opacity: 1}

Answer 1

Avoid positioning of the .title, and opacity.
.video_wrap{
width: 232px;
height: 232px;
border-radius: 50%;
overflow: hidden;
margin: 10px;
}
.related {
width: 232px;
height: 232px;
position: absolute;
border-radius: 50%;
overflow: hidden;
z-index: -1;
}
.img_wrap img {
height: 100%;
}
.title{
margin: 185px 0 0;
background: rgba(255,255,255,.5);
line-height: 50px;
text-align: center;
transition: all .5s ease-in;
}
.title:hover{
background: #fff;
}
<div class="video_wrap update">
<div class="related img_wrap"><img src="http://img.youtube.com/vi/XyzYVpJGRG8/hqdefault.jpg"></div>
<div class="title">
rikthejm na
</div>
</div>
