HTML naming conventions for ID, class and to include element type prefix? [closed]

Answer 1

A lot of people don't realize you can do this stuff:

.awesome {
 /* rules for anything awesome */
}

div.awesome {
 /* rules for only awesome divs */
}

button.awesome {
 /* rules for any awesome buttons, but not awesome divs */
}

div.awesome h1 {
 /* rules for H1s inside of any div.awesome */
}

div.awesome>button {
 /* rules for immediate children buttons (not grandchildren+) of div.awesomes */
}
