We use the custom layout to add messages to a whole Confluence site to say that the server will have downtime at some evening. We have noticed today that including that breaks sometimes the layout of the editor. Here is an example:
- Go to {{Administration > Layouts > Main Layout > Edit}}
- Add there at {{## HTML body begins}} the following lines of code:
<div style="color: #f33; font-size: 18px"> This system (including Subversion, Q-Base and JIRA) will go down for maintenance reasons on Aug. 8th. at 18:00.</div>
- Go then to a normal page in the edit mode.
- The editor buttons (Save and Cancel) are no more visible now.
Just to illustrate the problem, I have appended two screen shots of a small (but full functional browser window). Font size is 18px, and the moment the message goes to 2 lines, the buttons are gone.
