Hi, I believe you are talking about your <h1> tag moving around, which is not uncommon. (Like you have below)
<h1><font style="font-size:21px" color="#6B8ACE" face="Arial"><b>Copywriting & Content optimisation</b></font></h1>
Try this.
Place this 1st part of the code in the “Between the head” area of your page properties.
HTML Code:
<STYLE type="text/css">
h1 {font-size:21px;color:#C0C0C0;font-family:Arial MS;font-style:normal;margin:0px;}
</STYLE> Place this second part in a html box on the front of the page. (Preview)
HTML Code:
<h1>Copy writing and Content Optomization</h1>
