CSS Ellipsis Beginning of String

By  on  

I was incredibly happy when CSS text-overflow: ellipsis (married with fixed width and overflow: hidden was introduced to the CSS spec and browsers; the feature allowed us to stop trying to marry JavaScript width calculation with string width calculation and truncation.  CSS ellipsis was also very friendly to accessibility.

The CSS text-overflow: ellipsis feature is great but is essentially meant to ellipsize strings only at the end; what if we want to ellipsize the beginning of a screen?  The use case is fairly reasonable: think displaying a file path -- many times the directory for a set of files is the same, in which case you'd want to display the end of the string, not the beginning.

Let me show you a trick for ellipsis at the begging of the string!

The CSS

Showing an ellipsis at the front of a string is mostly the same as ellipsis at the end, only with one simple trick:

.ellipsize-left {
    /* Standard CSS ellipsis */
    white-space: nowrap;                   
    overflow: hidden;
    text-overflow: ellipsis;  
    width: 200px;
    
    /* Beginning of string */
    direction: rtl;
    text-align: left;
}

To add an ellipsis at the beginning of a string, use RTL and and text-align to clip the beginning of the string!

Playing RTL off of text-align is a genius way to get the desired effect of CSS ellipsis at the beginning of an element or string.  It would be great for the CSS spec to implement a more robust ellipsis system but, for now, I worship amazing CSS tricks like this!

  1. The CSS spec seems to recommend against using the direction property on web pages:

    This seems kind of strange. Where is the extra slash coming from?

    This trick seems to be broken for Safari which still truncates from the back then appends the ellipsis to the front.
