how to edit the icon of youtube?

Question

I'm new in the field of web designing. When I hear the inspect option in the browser, I think to change the youtube icon into mytube. Then, when I check the code of the icon I got a long data which I never see anywhere in my studying period. I attach that code with this. There are anyone who know to convert the letters y, o, u into m, y??

Answer 1

The long string is a list of path commands. Each letter followed by numbers decides how the path is drawn. You picked the letter "o" in YouTube.

You can edit an SVG document or element in an desktop editor like Illustrator or InkScape. For editing paths I often use an online editor like SvgPathEditor.

In the below example I copied the code for the YouTube icon. Using SvgPathEditor I scaled up and rounded all numbers to make the sting shorter.

<svg viewBox="0 0 290 200" width="300">
  <path d="M 280 31 C 276 19 267 9 254 6 C 232 0 143 0 143 0 
  C 143 0 54 0 31 6 C 19 9 9 19 6 31 C 0 54 0 100 0 100 
  C 0 100 0 146 6 169 C 9 181 19 191 31 194 C 54 200 143 200 143 200 
  C 143 200 232 200 254 194 C 267 191 276 181 280 169 
  C 286 146 286 100 286 100 C 286 100 286 54 280 31 Z" fill="#FF0000" />
  <path d="M 114 143 L 188 100 L 114 57 V 143 Z" fill="white"/>
