This is what I come up with. I'm unclear what the 4th requirement means, so I've labeled it #unclear.
a { color : red; }
p:not(:first-child) { text-indent: 5%; }
div { background-color: aqua; }
#unclear { width: 50%; margin-left: 25%; margin-right: 25%; }
.links:link { font-size 24px; background-color: yellow; }
#first { text-transform: uppercase; font-style: italic; }
<span>Virtual private network (VPN) is the answer</span>
