audit-avt1-homepage: more than one banner role

[andreancardona]

Environment:

Operating system: Mac
Browser: Chrome
AVT 1️⃣
Page: Homepage

Detailed Description:

There is more than one element with "banner" role on the page.

What to do:

Remove "banner" role from all but one element. (The

element has an implicit role of banner when it is a descendent of the body element.)

Why is this important?

When more than one "banner" landmark role is used on a web page, it can confuse people who use assistive technologies that rely on this information to easily navigate the various sections in the page.

Most sense: wrap BLM header into Carbon header
One solution - give BLM and Carbon header unique IDs
Other solution is to turn BLM header into a div

Also remove aria-label="Header" on header
