_text-clamp.scss

// Clamps a block of text to a certain number of lines,
// followed by an ellipsis in Webkit and Blink based browsers
// Reference: http://dropshado.ws/post/1015351370/webkit-line-clamp
@mixin text-clamp($lines: 2, $line-height: false) {
    overflow: hidden;
    display: -webkit-box;
    -webkit-box-orient: vertical;
    -webkit-line-clamp: $lines;

    // Fallback for non-Webkit browsers
    // (won't show `…` at the end of the block)
    @if $line-height {
        max-height: $line-height * $lines * 1px;
    }
}

This is perfect, love the fallback 👍

to keep the ellipsis:
text-overflow: ellipsis;

is there any properties for min 2 lines? (even if the text take space only for one line - the second was invisible)
