Subject: Documentation cleanup (inc. use of <input ... readonly> for static form controls... 
X-Git-Tag: v4.0.0-beta~166^2~72
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f7f644a4e52a7e875d5c8574d2a8b7fd919e5005;p=thirdparty%2Fbootstrap.git

Documentation cleanup (inc. use of <input ... readonly> for static form controls example)

* Fix incorrect code indentation
* Remove unnecessary vendor prefix for `box-sizing` - all modern browsers now support this unprefixed
* Remove incorrect `<label>` and change static controls to readonly inputs
* Allow `<img>` elements without `src` to allow for `holder.js` images used in the docs, which lack `src` and use `data-src` instead
