2nd try would lke feedback & what am I doing wrong? tia

On a first glimpse, you have lots of elements that aren’t closed properly or don’t have content inside. Take a look at this first bit of code you have: you have an empty h1 element, you have an empty header element with an improperly labeled id, you have multiple a elements that aren’t closed and that have improperly formatted href attributes…I didn’t go through the rest of the code after this. You should go back and fix all of these tag errors and look through the rest of your code before you do anything else.
