Why on Safari the transform translate doesn't

Question

I often use this code to center a div in view:

.centered {
  position: fixed;
  top: 50%;
  left: 50%;
  /* bring your own prefixes */
  transform: translate(-50%, -50%);
}

It works great on Firefox, Internet Explorer and Chrome, however not in Safari.

What's a workaround to center an image in Safari web browser?

Answer 1

Here is what works for me on all tested browsers and mobile devices (Chrome, IE, Firefox, Safari, iPad, iphone 5 and 6, Android).

The key for safari (including ios devices) is to add the other transform css rules and not just:

transform: translateY(-50%);

You need to add to it this group of rules:

-ms-transform: translateY(-50%);
-webkit-transform: translateY(-50%);
-moz-transform: translateY(-50%);
-o-transform: translateY(-50%);

Here is some working code of mine:

img.ui-li-thumb {
    position: absolute;
    left: 1px;
    top: 50%;

    -ms-transform: translateY(-50%);
    -webkit-transform: translateY(-50%);
    -moz-transform: translateY(-50%);
    -o-transform: translateY(-50%);
    transform: translateY(-50%);
}

Answer 2

You need another vendor prefixed style.

.centered {
  position: fixed;
  top: 50%;
  left: 50%;
  /* bring your own prefixes */
  -webkit-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
}

Please refer below to know which browser supports what and what prefix has to be added. http://caniuse.com/#feat=transforms2d

Answer 3

In some cases you'll have to use:

-webkit-transform: translate3d(-50%,-50%,0);

Sometimes works better with mobile browser.
