Answer 1

Have *you* used CSS on the page(s)?  You are the one in control of this.  If you have not used CSS on the pages, then you wouldn't have a CSS file into which you can put this rule.
Looking at the code on your page, I can see that you have embedded your CSS both in the non-editable and the editable parts of the template - so here is where you would put it -
<style type="text/css">
<!--
html { overflow-y:scroll; }
.style1 {
     font-family: Arial, Helvetica, sans-serif;
     color: #FFFFFF;
     font-weight: bold;
     font-size: 14px;
.style3 {
     font-family: Arial, Helvetica, sans-serif;
     font-size: 16px;
     font-weight: bold;
     color: #FFFFFF;
.style4 {
     font-family: "Times New Roman", Times, serif;
     font-weight: bold;
     font-size: 50px;
     font-style: italic;
     color: #999999;
.style5 {
     font-family: Arial, Helvetica, sans-serif;
     font-size: 12px;
     font-weight: bold;
.style6 {font-size: 14px}
.style7 {font-family: Arial, Helvetica, sans-serif; font-size: 14px; font-weight: bold; }
-->
</style>
Also looking at your code, I can see that you need lots of practice with your CSS as you are making many 'new at this' mistakes:
You are OVER defining content styles - there is no need to specify a font family or even font properties for every rule.  Often a single font declaration can cascade throughout your page by placing it on the body tag.
You are using the Property inspector to apply your styles - get out of this habit and learn how to use the CSS panel instead.
You are using classes for everything - get out of this habit and learn how to begin using containers, container id values, and descendent selectors.  There is nothing more daunting than trying to troubleshoot a page that contains hundreds of class attributes in the CSS.
Paying attention to these three elements will make your pages leaner, and much easier to troubleshoot.
