Modify CSS : Footer and in my last block

Hi IshYo,

I have 2 questions about the CSS for my footer first:

I’d like to have my text without lign between my block text, how can i delete that?
You can see my footer here : https://00ecb7657a.url-de-test.ws/
In my mind i’d like to have my links More ready from each other and centered, it’s possible?

And in second always through this link: https://00ecb7657a.url-de-test.ws/ you can see my last block with pictos before the footer and I shall like having less space between these pictograms, it’s possible?

Thanks so much,
best regards, Tiphaine
