# Rules
The headings SHOULD allow for overview and not create noise. 
If it is a visually-whole section is not a control then it MUST have a heading to act as a label. 
* There MUST be exactly one single h1 level per page. This is not necessarily the first element. 
* Nesting SHOULD not have holes in it like h3 following h1 or h5 following h3 . 
* The Breadcrumb no longer bears an h2 and thus h2 is freed up for use. 
* Same UI-Elements MUST have the same headline level throughout ILIAS.
