加载微调器上的AJAX

I'm wanting to place something like this on my website. Here is the codepen.

@-webkit-keyframes rotate-forever {
  0% {
    -webkit-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -ms-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    transform: rotate(0deg);
  }
  100% {
    -webkit-transform: rotate(360deg);
    -moz-transform: rotate(360deg);
    -ms-transform: rotate(360deg);
    -o-transform: rotate(360deg);
    transform: rotate(360deg);
  }
}
@-moz-keyframes rotate-forever {
  0% {
    -webkit-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -ms-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    transform: rotate(0deg);
  }
  100% {
    -webkit-transform: rotate(360deg);
    -moz-transform: rotate(360deg);
    -ms-transform: rotate(360deg);
    -o-transform: rotate(360deg);
    transform: rotate(360deg);
  }
}
@keyframes rotate-forever {
  0% {
    -webkit-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -ms-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    transform: rotate(0deg);
  }
  100% {
    -webkit-transform: rotate(360deg);
    -moz-transform: rotate(360deg);
    -ms-transform: rotate(360deg);
    -o-transform: rotate(360deg);
    transform: rotate(360deg);
  }
}
.loading-spinner {
  -webkit-animation-duration: 0.75s;
  -moz-animation-duration: 0.75s;
  animation-duration: 0.75s;
  -webkit-animation-iteration-count: infinite;
  -moz-animation-iteration-count: infinite;
  animation-iteration-count: infinite;
  -webkit-animation-name: rotate-forever;
  -moz-animation-name: rotate-forever;
  animation-name: rotate-forever;
  -webkit-animation-timing-function: linear;
  -moz-animation-timing-function: linear;
  animation-timing-function: linear;
  height: 30px;
  width: 30px;
  border: 8px solid #ffffff;
  border-right-color: transparent;
  border-radius: 50%;
  display: inline-block;
}

body {
  background: #774CFF;
}

.loading-spinner {
  position: absolute;
  top: 50%;
  right: 0;
  bottom: 0;
  left: 50%;
  margin: -15px 0 -15px;
}

<body>
  <div class="loading-spinner"></div>
</body>

However, I'm wanting this to display until all my ajax has loaded on my site, I have 5-6 API GET calls, and one by rails. How would i go about this? So that it covers the whole page until its loaded.

</div>

Convert the .loading-spinner to be a mask (see the code) so it will hide the content.
When ajax done just .hide() it.

$.ajax({
  url: 'your_ajax',
  success: function() {
    hideLoader()
  },
  error: function() {
    hideLoader()
  }
});

function hideLoader() {
  $('.loading-spinner').hide();
}

    -webkit-transform: rotate(0deg);
    -moz-transform: rotate(0deg);

    transform: rotate(0deg);
  }
  100% {
    -webkit-transform: rotate(360deg);
    -moz-transform: rotate(360deg);
