sometimes the background picture encoded by base64 is used, which makes a line of code too long. Can css wrap it?
&.sort > span::after {
background-image: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAwAAAAMCAYAAABWdVznAAAAAXNSR0IArs4c6QAAAE5JREFUKBVjYBj6gLEBCP7//19PjFcYGRkbmQ8AgaOjIyNQgwM+TSDFIMOZQYoIaYIpBqkFa8CnCVkxigZsmtAVg9RgBSC3ggBWSZoLAgBKkiQut6E4vQAAAABJRU5ErkJggg==);
}the editor can adjust the line break mode, which is more convenient.
you can change your line if you have to. Just add a \ backslash at the end of the newline of the string.
.xx {
background-image: url(
'data:image/png;base64,iVBORw0KGgoAAAANSUhEUg\

);
}
