Hello, i know how to change text bgcolor in XWiki source content mode, but i don’t know how to change it in WYSIWYG mode. I haven’t some button to set bgcolor for some text fragment.
I found only button for change style to preset, e.g. highlight style, but it makes bgcolor yellow and i need different bgcolor for text of the page.
Can somebody help me change text’s bgcolor in WYSIWYG mode of CKEditor?
UPD: i mistaken it mean CKEditor
TinyMCE? XWiki doesn’t use that WYSIWYG editor anymore since… more than 10 years ago 
In any case this is clearly not supported, see https://www.xwiki.org/xwiki/bin/view/Main/Support#HSupportedVersions
Or maybe you meant CKEditor?
My mistake i meen CKEditor
ok 
I’ve googled and found Change the background color of the CKEditor text area | CKEditor.com Forums
Then see https://extensions.xwiki.org/xwiki/bin/view/Extension/CKEditor%20Integration/#HCustomization
Hope it helps
