[BUG] [Idea] Navbar issue and ecosystem list

[Joelarias1]

Hello everyone, there are a few small fixes I would like to propose. First of all on the main page the navbar, when I press the Develop button at the top of the page the dropdown has no background so it is below the first text titles.

Another is that if I open the All Networks button to select whether testnet or mainnet, it happens that when I scroll down or up it locks completely.

I would also recommend to put a more subtle button for the social network X, or the one you have directly, because the "X" logo next to the name gets lost.
