I'm looking for a way to overlay a video with a semi-transparent black div that includes text and a button, while still allowing users to see the video playing behind it. I previously achieved this using a PNG image but now need to apply the effect to a button as well. I'm considering using SVG but am unsure of how to implement it. Any advice or guidance would be greatly appreciated. Thank you.
One way to achieve this effect is by using an SVG image overlay on top of the background.
.wrapper {
position: relative;
}
.wrapper svg {
position: absolute;
left: 0;
top: 0;
}<div class="wrapper">
<img src="http://lorempixel.com/640/480"/>
<svg id="overlay" width="640" height="480" viewBox="0 0 640 480">
<defs>
<mask id="mymask">
<rect width="100%" height="100%" fill="white"/>
<text x="320" y="140" text-anchor="middle" font-size="40px" >Some transparent text</text>
<text x="320" y="190" text-anchor="middle" font-size="40px" >has been placed here</text>
<rect x="220" y="300" width="200" height="50" fill="black"/>
<text x="320" y="335" text-anchor="middle" fill="white" font-size="30px">BUTTON</text>
</mask>
</defs>
<rect fill="black" fill-opacity="0.7" width="100%" height="100%" mask="url(#mymask)"/>
</svg>
