HTML comments causing an issue exporting CSS files with Grunt-usemin
问题 I'm using yeoman/grunt to for my build process and I'm running into an issue. I'm trying to build two .css files, one for IE8 and one for everything else. If I place the IE conditional on the outside of the build block, an error is thrown because of the comment within a comment. If I put the IE conditional on the inside it gets stripped out. <!--[if lte IE 8]> <!-- build:css({.tmp,app}) styles/main-old-ie.css --> <link rel="stylesheet" href="styles/main-old-ie.css"> <!-- endbuild --> <![endif
