Today I want to share little css tip for styling the suiteBar in SharePoint 2013 and making it work even in IE8. I needed to apply a green color to the suiteBar (#005128). It worked in all browsers except IE8: The reason why is a special css rule (in corev15.css) that only IE8 understands: [sourcecode language=“css”] .ms-core-needIEFilter #suiteBarLeft { filter: progid:DXImageTransform.Microsoft.gradient(GradientType=0,startColorstr=#ff0072c6,endColorstr=#ff0072c6); } [/sourcecode] I found this answer in an blog post written by Trace Armstrong: SharePoint 2013 – Branding the Top Bar and the Importance of Browser Testing.
