Hello All,

I am having a master page on which i have a button and on clicking the button font size will increase through javascript function like

Master Page

<body id="sitebody1">

onclick="set_font_size('increase')

Javascript

function set_font_size(fontType) {
if (fontType == "increase") {
if (fontSize < 100) {
fontSize = parseInt(fontSize) + 15;
}
} else {
fontSize = 75;
}
document.getElementById("sitebody1").style.fontSize = fontSize + "%";

It works fine with the controls exits on master page but it is not increasing size of content page's control because i am using page wise style like

Content Page

CSS

.style43
        {
          font-size: small;
            
        }

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="Main">

Welcome

So i want to override the content page style property from master page's javascript function.
Please help!!!
