Problem

We love confluence and gliffy diagrams!  However, while evaluating confluence and some add-ons (including gliffy) there are some fairly annoying notices displayed on many confluence pages about a trial license and that we should buy them (which we have!).  While we were waiting for our finance department to approve our confluence and gliffy diagram licenses I got sick of seeing these and decided to hide them.  I'm making it clear though that we have purchased licenses now and hence I've removed these CSS components (as they are no longer needed).

Solution

In Confluence settings global stylesheets (General configuration → Stylesheet) add (some of) the following:

/* hide confluence evaluation message */
p.license-eval{
    display:none;
}

/* the create more button to have three BLACK icons */
.aui-iconfont-more:before{
    color : black;
}

/* hide google-docs/videos ad when using ie */  
div[aria-label*="To use Docs offline, upgrade to Chrome"]{  
    display: none;  
} 

/* Makes all Canvas boards fill width of page */
.adhocboard[id^=board-]{
    max-width : none;
}

/* Hide gliffy number of days left */
div.gliffy-webpanel-footer{
    display:none;
}

/* Hide Gliffy trial notice */  
.aui-message.shadowed.closeable{  
    display : none;  
}  

/* Hide Gliffy edit icon - has issues where should only edit in edit mode */
.gliffy-item.gliffy-button.gliffy-edit.gliffy-item-left{
    display : none;  
}

/* Hide Gliffy embed icon - don't want that functionality */
.gliffy-item.gliffy-button.gliffy-embed{
    display : none;  
}
