For the Open Web Camp attendees, here’s my cheatsheet from the Refactoring for Mobile talk I gave today at Stanford:

Get it as a CSS file and view it in your favorite code editor:

walkthrough.css

Or preview here:


/*
The first thing we need is a media query and to add
<meta name="viewport" content="width=device-width,
minimum-scale=1.0, maximum-scale=1.0">
to the head:
*/
@media only screen and (max-device-width:480px) {
/*
For starters, note the two divs #wrapper and #contents.
Let's use those to create our structural layout and
fold back in some of those design elements.
*/
#wrapper {
background:url(img/back2.png) no-repeat center top;
margin-top:-1em;
}
#contents {
text-align:left;
width:95%;
margin:0 auto;
}
/*
Now, let's style the main navigation buttons. First, we
will use inline-block to give block-like behavior to the
buttons but retain width based on the content. Then we set
the color, font size, and floating, and add a bit of box
shadow.
*/
.menu a {
display:inline-block;
background-color:#000;
float:left;
font-size:14px;
padding:1em 0.95em;
border-left:1px solid #888;
-webkit-box-shadow:0px 1px 5px #222;
}
/*
We can now use border-radius to style the left and right
buttons instead of image files:
*/
.first_menu a {
border-bottom-left-radius:6px;
border-left:none;
margin-left:2px;
}
.menu li:last-child a {
border-bottom-right-radius:6px;
}
/*
What if we flip to Landscape? There's a media query for
that:
*/
@media screen and (orientation:landscape) {
.first_menu a {
margin-left:78px;
}
}
/*
Now we can style the body content. #middle-contents is
the main containing block. We can use the background image
from the main stylesheet, but alternately we can use rgba
backgrounds to get finer control. Add border radius and box
shadow for depth.
*/
#middle-contents {
/* background:url(img/side.png) repeat-y;*/
background-color:rgba(0,0,0,0.3);
padding:1em;
border-radius:10px;
-webkit-box-shadow:0px 1px 6px #000;
box-shadow:0px 1px 6px #000;
font-size:1.2em;
margin-bottom:1em;
}
/*
Let's style the banner text and have some fun with it using
web fonts. Here's a font we'll pull in, using TTF and SVG formats.
Sadly, the vendors have many opinions on the solution, but
FontSquirrel can help sort it out.
*/
@font-face {
font-family:'Lobster';
src: url('Lobster_1.3-webfont.ttf') format('truetype'),
url('Lobster_1.3-webfont.svg#webfontcOtP3oQb') format('svg');
}
#logo a {
display:block;
text-align:center;
padding-top:12px;
font-family:Lobster, sans-serif;
font-size:2.7em;
text-shadow:0px 2px 4px #000;
}
#logo h1 {
font-family:Lobster, sans-serif;
text-align:center;
font-size:1.5em;
}
/*
The float is creating a spacing issue. We can fix that
with a clear:
*/
#header { clear:both; }
/*
We are getting close. Now on to the bottom of the page.
The #comments section is too wide. We need to reset it:
*/
#comments {
width:100%;
}
#comments textarea, #comments input {
width:93%;
margin-bottom:0.5em;
padding:0.5em;
font-size:1.2em;
border:1px solid #000;
border-radius:6px;
}
/*
That input button could be nicer:
*/
#comments input.button {
display:block;
width:80%;
margin:0 auto;
height:2.5em;
padding:0.5em;
}
/*
Now we have something that looks like it was meant for a
mobile device. Let's wrap this up by making the final
links look like tap-friendly buttons:
*/
#right-col a {
display:block;
padding:0.5em;
font-size:1.3em;
font-weight:bold;
text-align:center;
background-image: -webkit-gradient(linear, left top, left bottom,
from(#666666), to(#666666), color-stop(.5,#333));
border:1px solid #000;
border-radius:20px;
margin-bottom:0.4em;
}
/*
Maybe those final link items were over the top.
Let's restore them to inline links:
*/
#copyrights a {
display:inline;
margin:0;
padding:0;
font-size:small;
border:none;
background-image:none;
}
}
/*
Now add some HTML5: Add placeholder="I think..." to the textarea in
comments.php, line 191.
Add input types to email and url fields.
Finish with atouch icon: <link rel="apple-touch-icon" href="piano.png"/>
(Note to attendees: I forgot to add the piano.png file to my project files.
But this works otherwise!)
