Css Form Layout

I have a css/jquery form that I need the css repaired and javascript added to. My radio button and checkboxes do not look good and when the correct value is entered I want the font to turn green!

I already have a the code for the valid state

if(First_Name.val().length < 1){

First_Name.addClass(“error”);

First_NameInfo.text(“*First Name?”);

First_NameInfo.addClass(“error”);

return false;

}

//if it’s valid

else{

First_Name.removeClass(“error”);

First_NameInfo.text(“*First Name?”);

First_NameInfo.removeClass(“error”);

return true;
}

}
