UPDATE
Just wanted to share and demonstrate 4 other general centering solutions
- FLEX:
.wrapper {
display: flex;
justify-content: center;
align-items: center;
height: calc(100vh - 20px);
background: red;
}
.inner {
background: green;
color: white;
padding: 12px;
}<div class="wrapper">
<div class="inner">INNER CONTENT</div>
</div>- GRID:
.wrapper {
display: grid;
place-items: center;
height: calc(100vh - 20px);
background: red;
}
.inner {
background: green;
color: white;
padding: 12px;
}<div class="wrapper">
<div class="inner">INNER CONTENT</div>
</div>- SAME HEIGHT AND LINE HEIGHT + TEXT ALIGN
.wrapper {
line-height: calc(100vh - 20px);
height: calc(100vh - 20px);
text-align: center;
background: red;
}
.inner {
background: green;
color: white;
padding: 12px;
display: inline;
}<div class="wrapper">
<div class="inner">INNER CONTENT</div>
</div>- USING ABSOLUTE, TOP, LEFT and TRANSFORM TRANSLATE
.wrapper {
height: calc(100vh - 20px);
background: red;
position: relative;
}
.inner {
background: green;
color: white;
padding: 12px;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}<div class="wrapper">
<div class="inner">INNER CONTENT</div>
</div>This CodePen helped me to create a page-centered spinner with Material Design in Angular 4: https://codepen.io/MattIn4D/pen/LiKFC
Component.html:
<div class="loading-indicator">
<mat-progress-spinner mode="indeterminate" color="accent"></mat-progress-spinner>
</div>
Component.css:
/* Absolute Center Spinner */
.loading-indicator {
position: fixed;
z-index: 999;
height: 2em;
width: 2em;
overflow: show;
margin: auto;
top: 0;
left: 0;
bottom: 0;
right: 0;
}
/* Transparent Overlay */
.loading-indicator:before {
content: '';
display: block;
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: rgba(0,0,0,0.3);
}
