How do I position one image on top of another in HTML?
I'm a beginner at rails programming, attempting to show many images on a page. Some images are to lay on top of others. To make it simple, say I want a blue square, with a red square in the upper right corner of the blue square (but not tight in the corner). I am trying to avoid compositing (with ImageMagick and similar) due to performance issues.
I just want to position overlapping images relative to one another.
As a more difficult example, imagine an odometer placed inside a larger image. For six digits, I would need to composite a million different images, or do it all on the fly, where all that is needed is to place the six images on top of the other one.
Answer :
This is a barebones look at what I've done to float one image over another.
img {
position: absolute;
top: 25px;
left: 25px;
}
.imgA1 {
z-index: 1;
}
.imgB1 {
z-index: 3;
}<img class="imgA1" src="https://placehold.it/200/333333">
<img class="imgB1" src="https://placehold.it/100">
