Last tutorial, I showed you how to design a watercolor effect menu
in Photoshop. This tutorial I will show you how to slice up the menu
design (step by step) and put them together with CSS. Most of you
probably know how to code a horizontal or vertical CSS list menu. Now
let’s take it to the next level — code an advanced (un-typical) list
menu utilizing the CSS position
property.

Overview
Here are the required graphics to assembe the menu (you can download from the zip).
1. Main background
Open the Photoshop file. Turn off the menu text Layer Group and save the main background as menu-bg.jpg.
2. Button graphics
Turn off the background Layer Group and leave only the menu text
layers visible. Make a rectangle selection cover the "home" item, go to
menu Edit > Copy Merged (Cmd + Shift + C).
Create a new file and take note of the file dimension (w x h), in my
case the "home" graphic is 144 x 58px. Paste the "home" graphic in the
new file. Go to menu Image > Canvas Size, adjust the image height x
2 (58 + 58 = 116px). Duplicate the home graphic layer and align it to
the bottom. Erase the highlight strokes in the upper layer.
Here is how the hover effect will work. We will set the link button
to 144 x 58px, when mouseover, we will shift the background image from
top to bottom.
Repeat this step for the other buttons. You should have the follow graphics:
3. HTML source
When you are done with the graphics, let’s start coding. Start with an un-ordered list <ul>
.
- note there is an id="menu" assigned to the
<ul>
tag
- an unique class name assigned to each link
<a>
- an empty
<span>
tag (the purpose of this is to make the mouseover effect)
<ul id="menu">
<li><a href="#" class="home">Home <span></span></a></li>
<li><a href="#" class="about">About <span></span></a></li>
<li><a href="#" class="rss">RSS <span></span></a></li>
</ul>
#menu
Reset the menu to no padding, no margin, and no list-style. Specify
the width and height same dimension as the menu-bg.jpg. Then attach the
menu background image. The key point to remember here is set the position
property to relative
.
#menu {
list-style: none;
padding: 0;
margin: 0;
width: 774px;
height: 210px;
background: url(images/menu-bg.jpg) no-repeat;
position: relative;
}
#menu span
Specify the span
element to display:none
(so they will be invisible by default). Specify position:absolute
, so we can place the mouseover GIF image on exact position.
#menu span {
display: none;
position: absolute;
}
#menu a
The key point here is the text-indent
property. We specify the text-indent
property with a negative value (-900%), so the text will be hidden.
#menu a {
display: block;
text-indent: -900%;
position: absolute;
outline: none;
}
#menu a:hover
When mouseover the link, we want to shift the background image from top to bottom.
#menu a:hover {
background-position: left bottom;
}
#menu a:hover span
When mouseover the link, we want the span
element to display:block
.
#menu a:hover span {
display: block;
}
#menu .home
Specify the width, height, and background image. Since we already specified all <a>
element postition:absolute
in previous step, now just say where the .home button should be by specifying the left and top property.
#menu .home {
width: 144px;
height: 58px;
background: url(images/home.gif) no-repeat;
left: 96px;
top: 73px;
}
#menu .home span
Here we are specifying the width, height, background, and position of the span
element of .home (mouseover GIF image)
#menu .home span {
width: 86px;
height: 14px;
background: url(images/home-over.gif) no-repeat;
left: 28px;
top: -20px;
}
#menu .about
Copy the .home rules and rename them to .about. Now just change the width, height, background, left, and top property.
#menu .about {
width: 131px;
height: 51px;
background: url(images/about.gif) no-repeat;
left: 338px;
top: 97px;
}
#menu .about span {
width: 40px;
height: 12px;
background: url(images/about-over.gif) no-repeat;
left: 44px;
top: 54px;
}
#menu .rss
Repeat this step for .rss
#menu .rss {
width: 112px;
height: 47px;
background: url(images/rss.gif) no-repeat;
left: 588px;
top: 94px;
}
#menu .rss span {
width: 92px;
height: 20px;
background: url(images/rss-over.gif) no-repeat;
left: 26px;
top: -20px;
}
All in one:
#menu {
list-style: none;
padding: 0;
margin: 0;
width: 774px;
height: 210px;
background: url(images/menu-bg.jpg) no-repeat;
position: relative;
}
#menu span {
display: none;
position: absolute;
}
#menu a {
display: block;
text-indent: -900%;
position: absolute;
outline: none;
}
#menu a:hover {
background-position: left bottom;
}
#menu a:hover span {
display: block;
}
#menu .home {
width: 144px;
height: 58px;
background: url(images/home.gif) no-repeat;
left: 96px;
top: 73px;
}
#menu .home span {
width: 86px;
height: 14px;
background: url(images/home-over.gif) no-repeat;
left: 28px;
top: -20px;
}
#menu .about {
width: 131px;
height: 51px;
background: url(images/about.gif) no-repeat;
left: 338px;
top: 97px;
}
#menu .about span {
width: 40px;
height: 12px;
background: url(images/about-over.gif) no-repeat;
left: 44px;
top: 54px;
}
#menu .rss {
width: 112px;
height: 47px;
background: url(images/rss.gif) no-repeat;
left: 588px;
top: 94px;
}
#menu .rss span {
width: 92px;
height: 20px;
background: url(images/rss-over.gif) no-repeat;
left: 26px;
top: -20px;
}
Done
That’s it. You can preview my CSS menu.
Note: there is an IE6 bug where the <span> hover effect
doesn’t display properly. To fix that, you can use Javascript to
specify the <span> to display block on mouseover.
