Change font size of header phone number

yigit,

how do i add this code to the phone number? i am tracking when people on mobiles click on the phone number on top.
i figure that i need to add some sort of code to the phone number link maybe? but not sure how.

Thanks!

<!– Google Code for calls from cellphone Conversion Page
In your html page, add the snippet and call
goog_report_conversion when someone clicks on the
phone number link or button. –>
<script type=”text/javascript”>
/* <![CDATA[ */
goog_snippet_vars = function() {
var w = window;
w.google_conversion_id = 1052668207;
w.google_conversion_label = “hIknCMOuhGkQr-L59QM”;
w.google_remarketing_only = false;
}
// DO NOT CHANGE THE CODE BELOW.
goog_report_conversion = function(url) {
goog_snippet_vars();
window.google_conversion_format = “3”;
var opt = new Object();
opt.onload_callback = function() {
if (typeof(url) != ‘undefined’) {
window.location = url;
}
}
var conv_handler = window[‘google_trackConversion’];
if (typeof(conv_handler) == ‘function’) {
conv_handler(opt);
}
}
/* ]]> */
</script>
<script type=”text/javascript”
src=”//www.googleadservices.com/pagead/conversion_async.js”>
</script>

How do you style the phone number once you make it a hyper link with <a>
also, how to style the color for the hover?
thanks

This did not work for our site,
Probably the phone number tag has changed?

.phone-info …?
