    As a whole class itself you named as "button gray symbol" and "button blue symbol".
    So why not in css section you compose a entire class part in a name of ".button gray symbol " and " .button blue symbol " respectively and then you can add more property in those section as mouse hover or color changing ??
    If I compose a class in your css and add such property as follows

    .button gray number: mouse hover {

    background color= "red " ;
    }

    Is it wrong ??
