First off, make sure you are using the "Blank" style. The trick to making a borders around your front page is using background images or colors and HTML tables. To do that You'll have to insert code in to the HTML ( button in your editor).

You can change any item in red on all of the following code examples.

The first step is to set the background of the page. You can do that by inserting this code at the top:
<STYLE TYPE="text/css">
BODY {
background-image: url(http://www.babyhomepages.net/picture/?pid=0000000);
}
</STYLE>

If you do not want to use a image in the background replace the "background-image" line above with this:
background-color: red;

Now, to create the borders you'll have to insert the HTML code below. To make the borders wider increase the "cellspacing" value. To use a picture as the border change the value of "background" to the picture that you want to use. This example uses two borders. You can use as many as you want. Just make sure you have as many "</td></tr></table>" at the bottom of your page as you have "<table>" at the top.

<table cellspacing=15 cellpadding=0 width="100%" background="http://www.babyhomepages.net/picture/?pid=1111111" border=0><tr><td>

<table cellspacing=15 cellpadding=0 width="100%" background="http://www.babyhomepages.net/picture/?pid=2222222" border=0><tr><td>

THIS IS THE MAIN PART OF YOUR PAGE

</td></tr></table>

</td></tr></table>

If you want to use a color instead of a picture as the border change:
background="http://www.babyhomepages.net/picture/?pid=1111111"
to:
bgcolor="red"
