1a. Insert jQuery Code

First, download a copy of jQuery. In between the <head> tag, insert the jQuery code:

The jQuery will output the source code as:

1b. CSS Code

Style the <li> element with a background image accordingly (step1.png, step2.png, step3.png, and so on..).

#step .item1 {
background: url(step1.png) no-repeat;
}
#step .item2 {
background: url(step2.png) no-repeat;
}
#step .item3 {
background: url(step3.png) no-repeat;
}

2a. Add Sequential Content

You can also use this technique to add sequential content using jQuery’s prepend feature. The following example shows how you can add a counter number to a comment list.

The code will add the <span class="commentnumber"> tag (with # + 1) to each <li> tag.

2b. CSS

Style the <li> element with position:relative and use position:absolute to place the .commentnumber to the top right corner.

#commentlist li {
position: relative;
}

#commentlist .commentnumber {
position: absolute;
right: 0;
top: 8px;
}
