This is the format of the style.css file needs to be if you wish to use a custom css sheet for indicating and displaying diffs in AWB.

Create a file called "style.css" and put it in your AWB directory (same directory as AutoWikiBrowser.exe), you can then use the custom CSS.

Current style edit

From AWB 5.4.0.0 onwards the MediaWiki blue diff style is used.

/* suppress whitespace padding by C# WebBrowser, see
http://stackoverflow.com/questions/15033023/white-space-padding-in-webbrowser-control */
html,
body {
    margin: 0;
}

    width: 48.5%;
}

table.diff td div {
    /* Force-wrap very long lines such as URLs or page-widening char strings.*/
    word-wrap: break-word;

    /* As fallback (FF<3.5, Opera <10.5), scrollbars will be added for very wide cells
       instead of text overflowing or widening
    */
    overflow: auto;
}

Old style edit

This is the old standard/default AWB style for versions up to 5.3.1.0 (yellow/red/green):

td{
	border: 1px solid white;
}

table.diff, td.diff-otitle, td.diff-ntitle {
	background-color: white;
	border: 1px solid gray;
        font-family: Arial, san-serif; font-size: 12pt;
}
td.diff-addedline {
	background: #cfc;
	font-size: smaller;
}
td.diff-deletedline {
	background: #ffa;
	font-size: smaller;
}
td.diff-context {
	background: #eee;
	font-size: smaller;
}
.diffchange {
	color: red;
	font-weight: bold;
	text-decoration: none;
}

td.diff-deletedline span.diffchange {
	background-color: #FFD754; color:black;
}

td.diff-addedline span.diffchange {
	background-color: #73E5A1; color:black;
}

.d{
	overflow: auto;
}
