Todo app (HTML, CSS, JS)

I tried to input the close button svg using svgsprite to change the color on hover, but when I did it the element was there but you couldn't see the icon, so I changed it back to a regular img.

Another problem I had is that I could load tasks from local JSON but not save them, I looked it up on google but everywhere I looked people were using node, so if someone knows any other way I could do that I would be grateful if someone could tell me.

Otherwise it was a very fun project.
