    -webkit-touch-callout: all; /* iOS Safari */
    -webkit-user-select: all; /* Safari */
    -khtml-user-select: all; /* Konqueror HTML */
    -moz-user-select: all; /* Firefox */

Just by adding that CSS and adding the class selectable to your HTML element will highlight all the inner HTML. Then the user can press ctrl+c to copy the text without needing to highlight everything. This has a very nice effect on your mobile devices. It will highlight everything on your phone which is very convenient
