SOLVED: Using absolute positioning to center a div class in the middle

I’m having trouble centering this div class in the middle.

It keeps staying centered at the top, and not the middle.

I can’t figure out how to position it in the middle.

How it works is, you click on the play image and it opens up.

The rectangle of the same width and height, should be in the middle.

.wrap {
  position: absolute;
  left: 0;
  top: 0;
  right: 0;
  bottom: 0;
  margin: auto;
  width: 100%;
  height: 100%;
  overflow: hidden;
  border-radius: 25px;
  border: 3px solid red;
  box-sizing: border-box;
}

What did I do wrong?

Im relatively new to web dev, however have you tried using 50% on top and left properties and transform: translate by -50%.

I don’t believe that way worked for me.

Hello @javascriptcoding5678,

I found that this website helped me center elements with position: absolute. Maybe try to use that method and I hope it helps.

-Bryan

It seems that the problem is not with div.wrap but everything before it. There are multiple divs with position absolute and ratio keeper has a padding top that moves the effective top of that container down instead of around it.

Start with adding display: grid; place-items: center; onto the style of div.container.
If that works with you we can start working from there.

You need a fixed height on .container. You can use height: 360px as that seems to be the aspect ratio you are going for.


But I wouldn’t be centering it like that. The code you posted is kind of out of context and without any actual content just a bunch of containers. But here is an example with an alternate approach anyway.

https://jsfiddle.net/f7g6pjbk/

That still doesn’t fix it though, still not in the middle.

https://jsfiddle.net/fgayos9x/


.container {
  position: absolute;
  top: 0;
  left: 0;
  bottom: 0;
  right: 0;
  margin: auto;
  width: 100%;
  height: 360px;

}

.wrap {
  position: absolute;
  left: 0;
  top: 0;
  right: 0;
  bottom: 0;
  margin: auto;
  width: 100%;
  height: 100%;
  overflow: hidden;
  border-radius: 25px;
  border: 3px solid red;
  box-sizing: border-box;
}

It is in the middle until you shrink it down. It has to do with the way you are maintaining the aspect ratio.

Here it is with the way I did the aspect ratio in the other fiddle but with the original centering technique. I removed the ratio-keeper div.

https://jsfiddle.net/y5gL7t6d/


I’m not so sure you understand this centering technique which makes it harder for you to use. It’s a pretty odd technique and not one used that often. I’m not sure I would suggest using it for this.


Edit: You also seem to have an abundance of containers in your project. You should really make sure you are not unnecessarily using containers and nesting elements deeply. Your layout is just going to become unmanageable if you are not more careful about this.

This worked
