Hey,
A link to your site is really helpful when asking for custom css work. Here is some guesses please post a link if you have more or these don’t work.
1.
#containerfooter> .container {
width: 100%;
}
#containerfooter > .container .row {
max-width: 1170px;
margin: 0 auto;
}
.footercredits {
padding: 5px 15px;
margin: 10px -15px 0;
background: gray;
}
.footercredits p {
max-width: 1170px;
margin: 0 auto;
text-align: center;
}
2.
.topbarmenu ul li a:hover {
background: gray;
}
3. That isn’t an option with the free theme. You can do this in premium using pagebuilder and the premium themes carousel widget but in free the background only runs as wide as the page content.
