I saw @name (for example) @menu in css value. I noticed it is related to a php array but I dont know what is it exactly. Is it used for refer to the data structure in php code? Does @ means special thing or just a part of the value like a normal letter.
For example:
.menu .block {
background-color: @menucolor;
border-color: @menuborders;
}
When I search @ in css, I saw @rules in css. But I cannot find information about @ in css value. Anyone knows? Thanks.
