.def-font(@name) {
    @font-face {
        font-family: @name


Output: @font-face{font-family:font-a;}@font-face{font-family:font-a;}

Note the duplicated 'font-a'.

It's the @ in the @font-face that creates the problem.

Unfortunately I not familiar enough with the less.js internals to propose a patch.


Not really a bug.

You can use,

Can you show a definition of .def-font that would work correctly?


Perhaps something like this.

 .def-font(@name: "verdana") {
        @font-face {
            font-family: "@{name}";

That doesn't work. Same output as in the bug report. And I did try it before reporting too.


Confirmed now. I've ran through your provided use cases and it inspite of providing different argument values, it still outputs the first value that is provided to the mixin.

I also ran into this issue and here's the workaround I'm using:

.font-face(@name, @fn, @p) {
    font-family: '@{name}';
    src: url('@{p}/@{fn}-webfont.eot');
    src: url('@{p}/@{fn}-webfont.eot?#iefix') format('embedded-opentype'),
         url('@{p}/@{fn}-webfont.woff') format('woff'),
         url('@{p}/@{fn}-webfont.ttf') format('truetype'),
         url('@{p}/@{fn}-webfont.svg#@{name}') format('svg');
    font-weight: normal;
    font-style: normal;

Then simply wrap that function call in a @font-face block:

@font-face {
    .font-face('Verdana', 'verdana_font', 'fonts');

Not ideal, but it seems to work.


I had the exact same problem with @font-face and used your solution. Works perfectly, thanks!

If anyone wants to fix this in less.js I fixed it in the dotless port, its quite a simple bug.
