Menu
I want to display Angular Material's progress spinner when the page is initially loading, so I used the following code in my index file:
<body >
<app-root>
<md-progress-spinner mode="indeterminate">
</app-root>
</body>
When I do this, the spinner does not appear, however if I move the spinner to my app.component.html file, it does appear. Is it possible to get Angular Material progress spinners to work inside the index file? If so, how?

I think this will never work. Angular is still loading and so is Angular material. You'll need a pure CSS solution to display a spinner before Angular loads.
Some example in your index.html
<app-root>
<div class="app-loading">
<div class="logo"></div>
<svg class="spinner" viewBox="25 25 50 50">
<circle class="path" cx="50" cy="50" r="20" fill="none" stroke-width="2" stroke-miterlimit="10"/>
</svg>
</div>
</app-root>
<head>
<style type="text/css">
body, html {
height: 100%;
}
.app-loading {
position: relative;
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
height: 100%;
}
.app-loading .spinner {
height: 200px;
width: 200px;
animation: rotate 2s linear infinite;
transform-origin: center center;
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
margin: auto;
}
.app-loading .spinner .path {
stroke-dasharray: 1, 200;
stroke-dashoffset: 0;
animation: dash 1.5s ease-in-out infinite;
stroke-linecap: round;
stroke: #ddd;
}
@keyframes rotate {
100% {
transform: rotate(360deg);
}
}
@keyframes dash {
0% {
stroke-dasharray: 1, 200;
stroke-dashoffset: 0;
}
50% {
stroke-dasharray: 89, 200;
stroke-dashoffset: -35px;
}
100% {
stroke-dasharray: 89, 200;
stroke-dashoffset: -124px;
}
}
</style>
</head>
