ribbon hide my header

Hi

I’ve created a page (setting->add a page) and this page I created “Table of Contents” .

the way to do it is simple: I gave the title of the paragraph I want to link a bookmark name and in the Table of Contents I gave in the URL the bookmark name of the paragraph. this works great but one thing. I have a ribbon and when I click on the menu the header of the paragraph is behind the ribbon

anyone have an idea how to solve this problem?

thanks, Ilan
