CSS I want in BSS:
.btn-toggle::before {
width: 1.25em;
line-height: 0;
content: url(data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' width='16' height='16' viewBox='0 0 16 16'%3e%3cpath fill='none' stroke='rgba%280,0,0,.5%29' stroke-linecap='round' stroke-linejoin='round' stroke-width='2' d='M5 14l6-6-6-6'/%3e%3c/svg%3e);
transition: transform .35s ease;
transform-origin: 0.5em 50%;
}
BSS says “This property is invalid”:
PS: Do I have to add ::before
to a button or is it done automatically?
