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.
WOW nice rollover menu.. ^_^
You are a real artist! Amazing work!
Perfect tutorial! Thank you :)
Your tutorials are always so so helpful. Brilliant work as usual.
Now I must read it again for it to sink in. lol!
Thanks!
thx 4 your tutorial…so amazing….
That’s a great tutorial, but please, you may want to update “Start with an un-ordered list ” to say “Start with an un-ordered list “
Edit:
That’s a great tutorial, but please, you may want to update the “Start with an un-ordered list” piece so that it doesn’t use an OL tag but instal an UL tag.
Hi nice tutorial, however you made a mistake – may confuse some people – see below … you mention a un-ordered list but show the tag for an ordered list.
Great work though … keep it up!
This is a great tutorial, I have a slightly different way of doing the same thing. I place the span tags around the link text like this –> About
So when you declare – span {display:none} – it hides the text.
^ ^ Sorry that should say span>About/span>
Grr! How do you show tags using these comments??
Try this! <span> About </span>
Great tutorial!
Good to know.
You can achieve pretty much the same effect – but without the use of non-semantic span tags – by applying the background image directly to the a tag, and setting the width and height on that.
Unless I’m missing something specific with the span…?
Wonderfull job. Go on !
Actually, looking back at the code and what I just wrote – you’d need to do the following:
Combine the ‘out’ and ‘over’ graphics into a single image – ‘out’ state at the top, ‘over’ state at the bottom.
Use the css background-position property to set the background image at the top of the ‘a’ tag when it’s inactive, and set the background-position at bottom on the ‘a:hover’. You’ll need to check your specicivity to make sure the right image is displayed on the right li.
Set the display of the ‘a’ tags to ‘block’, and set the width and height (you may need to float the ‘li’s).
Set the text-indent on the ‘a’ tags to a fairly large negative number.
That *should* be your lot (although I’m probably missing something out!) – no non-semantic span tags, and single image rollovers which should save on both bandwidth and server requests (and make your css a tiny bit leaner).
Your tutorial has a typo:
3. HTML source
When you are done with the graphics, let’s start coding. Start with an un-ordered list .
Wow… this is great. I’ve only skimmed the coding but with all that positioning does the menu work correctly in every single browser/resolution combo?
I can’t wait to try this out though…!
excellent ! … je vais le tester tout de suite !
It’s funny you should post this, Nick – I posted my own very similar tutorial at the weekend! I think I prefer the way you’ve laid yours out, though, and the hover effect with the is a really nice touch. Well done… again! :)
Mike – You are correct. The added span and extra graphic can be consolidated to a single sprite graphic with less CSS required as you mentioned.
