<p>
<span data-scayt_word="[*introtext*]" data-scaytid="1">introtext</span></p>
<div id="partsbox">
That line of code is only for the page heading, which should be "Parts". So what you should have in the resource's 'introtext' fields is just Parts. The grey area is in this line of code and most probably meant to be taken from the resource's main Content field.
<div id="partsbox">
</div>
You cannot change the actual HTML and MODx tags of those HTML elements from the resource's editing fields, that is in the template. The template probably looks like this:
<p>
<span data-scayt_word="[*introtext*]" data-scaytid="1">[*introtext*]</span></p>
<div id="partsbox">[*content*]
</div>
So what you put in the 'summary (introtext)' field when editing the resource will appear where the [*introtext*] tag appears, and the resource's content will appear where the [*content*] tag appears. Usually you don't want to mess with the template; just put the heading you want in the summary or introtext field, and put the content the page should be showing in the grey section in the main content field.
