I have a task that requires parsing HTML pages and get all the tags with their attribute. Parsing an HTML page is not a big issue and I know many open source projects that can do the job. However, if an HTML tag use a CSS class or inherit attributes from a div tag that uses a CSS class then I will also need to get all the attributes from the CSS that the tag uses.

I have several custom HTML snippets for pieces of boilerplate HTML code I use often.
There are intended to be inserted somewhere in the DOM, such as a DIV.
However, they are being suggested when inside the quotes of an HTML attribute — where they can't be used — pushing down valid attribute selections.
How can I prevent this or, if not, disable intellisense for my HTML snippets altogether?
Thanks for your consideration about this problem.
I started to learn HTML and knew that there're many kinds of tags.
For example, such as (HTML), (head), (body), (a), (div), (table).
But I wonder if these codes can be used separately or should include (HTML), (head), (body) format always.
An HTML document has two* main parts:
head. The head element contains title and meta data of a web document.
body. The body element contains the information that you want to display on a web page.
* To make your web pages compatible with HTML 4, you need to add a document type declaration (DTD) before the HTML element. Many web authoring software add DTD and basic tags automatically when you create a new web page.
In a web page, the first tag (specifically, ) indicates the markup language that is being used for the document. The tag contains information about the web page. Lastly, the content appears in the tag. The following illustration provides a summary.
HTML, HEAD, BODY is requried - than all content you should write in BODY section

This gives a pretty thorough description of how HTML elements are interpreted by Markdown. But it does not discuss styles.
So far, the only thing I can get to work is image width.
I can't find a list anywhere of what is accepted/rendered
It appears that the style="....." attribute is completely ignored.
I can't even find a list of the old-fashioned style attributes (as opposed to the style attribute style=...)

Change span to div due to div being in the whitelisted tags per #waylan's comment under #chris's answer.
It appears that Firefox and Chrome don't render any style attributes any more at all.
After GitHub converts Markdown to HTML,
The HTML is sanitized, aggressively removing things that could harm you and your kin—such as script tags, inline-styles, and class or id attributes. See the sanitization filter for the full whitelist.
You're right: style tags are not included in the whitelist. They are ignored.
The permitted attributes differ by tag. I recommend referring to the sanitization filter link above. It leads to a fairly readable Ruby source file.
Where is the intellisense information stored for html tags? I'm creating custom tags and not sure how to create intellisense for the different attributes I would expect this custom tag to have. Since these tags I'm creating are not recognized as legit html tags when in fact I can still perform actions on them via JQuery, this is causing me some confusion as to how to get intellisense for attributes I create to show up.
I have this extension which injects HTML as a notification, the problem is that every site renders this HTML different since my HTML code inherits all the css rules.
so I wondered if there's a way to inject this HTML and keep it from rendering different in every website.
I would personally tag up all parts of my html and include inline css rules that specify exactly how I want the html to appear.
Not including any styling information puts you at the mercy of the designers od each site.
