    Simple CSS/HTML Question

    Hi everyone,

    Pretty basic question but I can't figure out how to achieve these for an assignment if someone wouldn't mind a quick pointer. I need to create three overlapping rectangles like shown:

    Thanks!

    To achieve that you just need to create 3 div elements, then use the background, width, height, position and top/left css styles to give the elements a background colour, give them a height/width so they're visible and then position them correctly.

    Here's a link to some documentation on the position style to get you started.

    You should look up "position" and "absolute" in a CSS manual. Absolute positioning allows you to position divs with "left" and "top" so they overlap.

    Hi there Minnesota31,

    and a warm welcome to these forums.

    As this is just an assignment, you might also want to entertain your tutor with a rather silly solution...
    Code:
    
    <!DOCTYPE html>
    <html lang="en">
    <head>
    
    <meta charset="utf-8">
    
    <title>silly solution</title>
    
    <style>
    #container {
        width:204px;
        padding:50px;
        border:1px solid #999;
        margin:auto;
        background-color:#9cf;
        box-shadow:5px 5px 5px #999;
        overflow:hidden;
     }
    #top-row {
        width:100px;
        height:50px;
        border:1px solid #fff;
        border-bottom:0;
        background-color:#f00;
     }
    #second-row-left {
        float:left;
        width:50px;
        height:50px;
        border-left:1px solid #fff;
        background-color:#f00;
     }
    #second-row-right {
