HTML and CSS: What do the <ul> and <li> tags mean?
3 answers
They focus on the elements <ul>and <li>on the page.
In CSS, the id has a prefix #, the class has a prefix ., and the element has no prefix.
Thus, the selector .sf-menu li:hover ulwill be applied to any element <ul>inside the element <li>that you are currently pointing to, inside element c class="sf-menu".
The selector .sf-menu li.sfHover ulapplies to any element <ul>, inside element <li>c class="sfHover", inside element c class="sf-menu".
