Javascript navigation hover effect

Question

Does anyone know how to implement the navigation hover effect displayed on this web page into my HTML/CSS document? The aforementioned page is using a WordPress theme, but I would like to add that green effect to my generic web page and be able to change the color as well.

PS I have never used Javascript before. (Be nice.)

Answer 1

Try This:

CSS

ul li{
 list-style:none;
}
ul li a{
transition:all 0.2s ease-out;
padding:5px;
border-radius:5px
}

ul li a:hover{
  background-color:#&dcc0e;
}

HTML:

<ul>
<li>
   <a>Hello</a>
</li>
</ul>

Answer 2

This does not need any js. You can create the effect using css transition like this.

 div{ width: auto; float: left; } a{ color: red; text-decoration: none; padding: 5px 20px; float: left; position: relative; } a:hover{ color:#FFF; } a:after{ content: ''; background: red; position: absolute; top: 50%; right: 5%; bottom: 50%; left: 5%; border-radius: 3px; transition: all .1s; z-index: -1; } a:hover:after{ top: 0; right: 0; bottom: 0; left: 0; } 

 <div><a href="javaScript:void(0);">menu</a></div>
