BaseUrl
The Base URL all URLS in the HtmlFragment will be relative to. This includes 'src' attributes on images, scripts, style-sheets and also hrefs on hyper-links.
Note: A base URL that points to a directory should end with a slash.

HtmlFragment
The HTML which will be used to render the Header or Footer should be an HTML snippet rather than a complete document. It may contain styles & images.
Merge meta-data into the HtmlFragment by putting any of these placeholder strings into the text: {page} {total-pages} {url} {date} {time} {html-title} {pdf-title}. An alternative mail-merge style using the pattern <span class='total-pages'></span> is also supported.
HtmlFragment is a stand-alone HTML document which does not inherit styles or settings from your
main HTML content unless LoadStylesAndCSSFromMainHtmlDocument is set true
Declaration
public string HtmlFragment { get; set; }

System.String |
LoadStylesAndCSSFromMainHtmlDocument
Loads style code blocks and links to CSS style sheets from the main HTML document (which provides the PDF content) into the HtmlHeaderFooter .
By default, HTML Headers and Footers are stand-
alone HTML documents with their own default styles. Setting LoadStylesAndCSSFromMainHtmlDocument to true
will attempt to load all STYLE and LINK tags
from the main HTML document (which renders teh PDF) into the HtmlHeaderFooter.
If your main HTML document contains complex CSS frameworks, styles the HEAD or BODY element heavily or loads CSS from javascript then this method may not work as intended.
This feature is not available for RenderUrlAsPdf methods. It works for RenderHtmlAsPdf, HTMLToPdf and HtmlFileToPdf conversions only.
It is often preferable to load style sheets explicitly into your HTML Headers and Footers as STYLE and LINK tags within the HtmlFragment for granular control
