Hey there! I'm fairly new to HTML and CSS, but I believe we can work on this together!
Your complete picture could be encompassed within a div that includes other window elements, with each window positioned in relation to the parent div.
.whole{
position:relative;
}
.UpperL{
position: absolute;
height: 25px;
width: 100px;
}
.UpperR{
position:...;
}
.LowerL{
position:...;
}
.LowerR{
position:...;
}
<div class="whole" img src="whole picture.png">
<!-- Make sure the whole class includes the background image-->
<div class="UpperL"> Upper Left Window</div>
<div class="UpperR"> Upper Left Window</div>
<div class="LowerL"> Upper Left Window</div>
<div class="LowerR"> Upper Left Window</div>
</div>
The code may not be perfect yet, but the idea behind placing four windows inside a fifth window is to allow the four windows to see through the fifth one;
If your parent div contains the image but appears white (opacity at 100%), the four window elements should be able to see through the opacity of the fifth window by reducing their own opacity to reveal the image.
hmm...
