Hi there,
1. This CSS should work:
.sf-menu.sf-arrows .sf-with-ul:after, .sf-menu.sf-arrows > li:hover > .sf-with-ul:after, .sf-menu.sf-arrows > .sfHover > .sf-with-ul:after, .sf-menu.sf-arrows > li > .sf-with-ul:focus:after, .sf-arrows .sf-with-ul:after {
display: none;
}
Then you need to normalize the padding on the right side of the menu item, so you would set it to default (20px) or something else if you’re using the Spacing addon and changed the size of your menu items.
Something like this:
.main-navigation .main-nav > ul.sf-arrows > li > a.sf-with-ul {
padding-right: 20px;
}
2. Copyright section may be a section I add to the plugin since it’s pretty crucial – this CSS should work:
.site-info {
font-size: 13px;
}
Change 13px to whatever you like.
3. They should all be identical – can you link me to your site so I can take a look?
To use the CSS above, either using a child theme or a plugin like: https://wordpress.org/plugins/simple-custom-css/
Hope this helps,
Tom
