<div class="row">
<div class="col-md-6 graph-column">
<div *ngIf="graphsLoaded">
<span class="graph-title">Players this month</span>
<mat-divider class="graph-divider"></mat-divider>
</div>
<div class="graph-content">
<canvas id="canvas-players">{{ players }}</canvas>
</div>
</div>
<div class="col-md-6 graph-column">
<div *ngIf="graphsLoaded">
<span class="graph-title">Server Uptime</span>
<mat-divider class="graph-divider"></mat-divider>
</div>
<div class="graph-content">
<canvas id="canvas-status">{{ status }}</canvas>
</div>
</div>
</div>


Graph loads fine, but what happens when you want to add a fade-in effect when the graph loads?



You do the following:



#canvas-players {
animation: anim 1s;
}

@keyframes anim {
0% {
opacity: 0.1;
}
100% {
opacity: 1;
}
}


Now when you load the page, one of your graphs should load with fade-in effect. OK it does!



img



But now when you resize your screen this is what happens:



img2



As you see, the first graph keeps it's original size, which is wrong, and the other graph is correct, resizing..



I tried to discover whats wrong, and it seems like it does not change the width and height attributes after using animation.



One interesting thing is, if I turn off the animation from inspect, and turn it back on, it will work just fine!



If I set width: 100% !important; and height: auto; to canvas, it will resize, but the whole canvas will be pixel'ed, according to the size.



I am wondering, if its a chartJs bug or a CSS bug?
