Answer:
HTML Link Colors
By default, a link will appear like this (in all browsers):
An unvisited link is underlined and blue
A visited link is underlined and purple
An active link is underlined and red
You can change the link state colors, by using CSS:
A patent grants the right to sell an invention and claim it as your own
Free space going around the town states
A device that sucks bc mien broke
If you mean sonar it uses echolocation but GPS is signaled from satellite to the internal antenna
