Animate background color like a progress bar in jQuery

Question

I have a div which has some text content( eg: My Name ) and the div is in RED background colour

Answer 1

This can be done using span changing its width over the time. Here is the working fiddle. The code is displayed below. Only the mandatory styles are displayed here.

HTML

      //this is the only additional line you need to add
    
Progress Button

Click Me

CSS

.red-button {
    position: relative;
    background: red;
}
span.bg-fix {
    display: block;
    height: 100%;
    width: 0;
    position: absolute;
    top: 0;
    left: 0;
    background: blue;
    transition: width 10s ease-in-out;
}
p {
    position: relative;
    z-index: 1
    width: 100%;
    text-align: center;
    margin: 0;
    padding: 0;
}

jQuery

$("div.red-button").click(function () {
  $('span.bg-fix').css("width", "100%");
});
