html {
overflow-y: scroll;
}This is invalid CSS, but it works in everything except Opera. The reason for this is to prevent "centering jumps" when navigating back and forth between pages with enough content to have a vertical scroll bar and pages that do not.
Firefox and IE have the "choose file" button to the right of the filepath, while Webkit puts it on the left. This makes WebKit put it on the right as well.
<input type="file">input[type="file"]{
-webkit-appearance: none;
text-align: left;
-webkit-rtl-ordering: left;
}
input[type="file"]::-webkit-file-upload-button{
-webkit-appearance: none;
float: right;
margin: 0 0 0 10px;
border: 1px solid #aaaaaa;
border-radius: 4px;
background-image: -webkit-gradient(linear, left bottom, left top, from(#d2d0d0), to(#f0f0f0));
background-image: -moz-linear-gradient(90deg, #d2d0d0 0%, #f0f0f0 100%);
}
A.K.A The "Clearfix" hack.
.clearfix:after {
visibility: hidden;
display: block;
font-size: 0;
content: " ";
clear: both;
height: 0;
}
.clearfix { display: inline-block; }
/* start commented backslash hack \*/
* html .clearfix { height: 1%; }
.clearfix { display: block; }
/* close commented backslash hack */Just apply a class="clearfix" to the parent element. This is an improved version of the original, and documented here.
Updated by Jeff Starr to be cleaner, based on the fact that nobody uses IE for Mac, which is what the backslash hack was all about.
.clearfix:after {
visibility: hidden;
display: block;
font-size: 0;
content: " ";
clear: both;
height: 0;
}
* html .clearfix { zoom: 1; } /* IE6 */
*:first-child+html .clearfix { zoom: 1; } /* IE7 */Updated again... "group" class name is nicer and more semantic (via Dan Cederholm). Content property doesn't even need the space, can be empty string (via Nicolas Gallagher). Without any text, font-size is un-needed (Chris Coyier).
.group:after {
visibility: hidden;
display: block;
content: "";
clear: both;
height: 0;
}
* html .group { zoom: 1; } /* IE6 */
*:first-child+html .group { zoom: 1; } /* IE7 */Of course if you drop IE 6 or 7 support, remove the associated lines.
.group:before,
.group:after {
content: "";
display: table;
}
.group:after {
clear: both;
}
.group {
zoom: 1; /* For IE 6/7 (trigger hasLayout) */
}Update August 2012: I'd say for the most part these days (if you only need IE 8 and up) this is fine:
.group:after {
content: "";
display: table;
clear: both;

You can flip images with CSS! Possible scenario: having only one graphic for an "arrow", but flipping it around to point in different directions.
img {
-moz-transform: scaleX(-1);
-o-transform: scaleX(-1);
-webkit-transform: scaleX(-1);
transform: scaleX(-1);
filter: FlipH;
-ms-filter: "FlipH";
}
* { margin:0; padding:0; }
html, body {
height: 100%;
}
body #fixedElement {
position:fixed !important;
position: absolute; /*ie6 and above*/
top: 0;
right: 0;
}
#page-wrap {
width: 600px;
margin: 0 auto;
font: 16px/2 Georgia, Serif;
}The 100% height on the body and html stuff is in case you want to do fixed positioning along the bottom edge of the browser window.
