I would remove…
<div class="image7">
…it is superfluous to requirements.
I would change all instances of “px units” to “em units”.
Fixed units do not allow the “window” to change it’s
dimensions when changing the “font-size”.
I would amend the CSS, where possible, to remove all
repetitions of code.
This is the result of those changes…

Finally, I would change your “window image” to the one that I made earlier…
