Bug: Extension crashes when user add a local background image file using CSS

[Droyk]

background-image: url('../background.png');
it crashes.

The reason I want to add a background using CSS it's because I want to add gradient to it.
background-image: url('../background.png'), linear-gradient(0deg, #5b4b87 0%, #222831 79%, #5a4b87 100%);

i don't think it's a bug. i think you just make some mistake on your css code.

1. you don't need to insert picture manually with css, just pick your picture normally thru background setting (gear icon) and then add your css code.
2. if you want to pick picture manually, you need encode the picture into base64 format or put external link of picture, you can't insert the picture by put the picture path on your computer into your css code like you did. try this
   html { background: url(put your base64 picture or link of picture); }
3. if you want to add the gradient effect your can try to use html:before for your gradient css code.

example:
html { background: url(https://wallup.net/wp-content/uploads/2015/12/111723-landscape-sunset-snow-material_style.jpg); }
html:before {
content: "";
position: absolute;
height: 100%;
width: 100%;
opacity: 0.5;
background: linear-gradient(
45deg,
#f09433 0%,
#e6683c 25%,
#dc2743 50%,
#cc2366 75%,
#bc1888 100%);
}
