Answer 1

Live Demo (Click the "Terms Div" text to test)

I didnt see the question tagged with jQuery, but I noticed a jQery selector was used.. so just to be safe I did it with pure JS anyway.

Pure JS

var terms = document.getElementById("termsCheckbox"),
    terms_div = document.getElementById("terms_div");

function validateTerms(){
    if(terms.checked == false){
        if(terms_div.className.indexOf("terms_error")<0){
            terms_div.className += " terms_error";
        }
        return false;
    }else{      
        terms_div.className = terms_div.className.replace(/\bterms_error\b/,'');
        return true;
    }
}
