How to move long text in headers to the next line on sidebar?

Question

Long headers of pages on left sidebar are not fully displayed its titles. They are displayed with ellipsis. To see the whole title I have to stretch the sidebar.

Confluence version 6.15.1.

How can I make the title of a long header automatically move to the next line?

Solve the problem by adding code: ".ia-fixed-sidebar div.plugin_pagetree ul.plugin_pagetree_children_list .plugin_pagetree_children_span a { white-space: normal; display: inline-block; }" into CSS Tables in Space tools.
