Arrows are repeatedly used in websites. We can use arrows in a website using:
1. Image
2. CSS
3. Symbol
Images are easy to use, but cost you more HTTP requests, and page your load times. Using CSS is a good approach, but it is bit complicated and may cost you some of your time. Time matters when you are working on a big project with short deadlines. So, using arrow symbol is pretty handy, easy to use and clever approach to use arrows.
