Question

I am trying to generate a menu like the following:

There are several items in the menu and the active one has an arrow after it.
The menu items are tags like the following code:

<div class="menuCenter">
     <div class="linksWrapper">
      <a href="#">Home</a>
      <a class="menuCenterLinkLeft" href="#">Plans & Pricing</a>
      <a class="menuCenterLinkLeft" href="#">Sign In</a>
      <a class="menuCenterLinkLeft active" href="#">Sign Up</a>
      <a class="menuCenterLinkLeft" href="#">Contact</a>
     </div>
</div>

I tryied two options:
1- Absolutely positioning the arrow image with javascript. I have problems when resizing the page.
2- Using the :after pseudo element, like this:

.linksWrapper a.active:after
{
    content: url("images/arrowImg.png");
    position: relative;
    left: -40px;
    top: 30px; 
}

The problem with this approach was the horizontal alignment of the arrow. It should be below the center of the link and I could not achive that.
I can use HTML5 or CSS 3.

Any help?

Answer 1

Try this:

.linksWrapper a.active:after {
    content: url("images/arrowImg.png");
    position: absolute;
    left: 50%;
    top: 30px;
    margin-left: - <width-of-your-image> / 2; /* negative number!*/
}

sidenote: I avoid putting { on a newline, since it may have nasty effects in javascript.

The trick is left:50%; combined with correcting the position by setting it back half width via margin-left.

See example.
