Overlay with spinner

Question

I\'m trying to create an overlay that overlays a page with a spinner in the middle. What\'s the simplest way to accomplish this? I only need to worry about IE 8 and above.

Answer 1

And for a spinner like iOs I use this:

html:

Css:

.spinner {
  font-size: 30px;
  position: relative;
  display: inline-block;
  width: 1em;
  height: 1em;
}

.spinner div {
  position: absolute;
  left: 0.4629em;
  bottom: 0;
  width: 0.074em;
  height: 0.2777em;
  border-radius: 0.5em;
  background-color: transparent;
  -webkit-transform-origin: center -0.2222em;
      -ms-transform-origin: center -0.2222em;
          transform-origin: center -0.2222em;
  -webkit-animation: spinner-fade 1s infinite linear;
          animation: spinner-fade 1s infinite linear;
}
.spinner div:nth-child(1) {
