[Beta] Remove CSS, Fix Sequencing Issues in Basic HTML & HTML5 Section

Challenge Name

This applies to ~2/3 of the challenges in the beta site Basic HTML and HTML5 section.

Issue Description

Now that the HTML and CSS challenges are in their own sections (with the HTML section sequenced first), the HTML challenges shouldn’t show any CSS since it hasn’t been taught yet. Also, there are some sequencing issues around the new challenges - the seed code doesn’t quite fit with the challenges before/after, or they introduce something new that isn’t carried to following challenges. For example, the Introduction to HTML5 Elements challenge’s seed code doesn’t quite match with the previous challenge, then it adds a main tag that isn’t carried forward. Here’s a list of all the challenges in the section and what should be fixed:

• Say Hello to HTML Elements
• Headline with the h2 Element
• Inform with the Paragraph Element
• Introduction to HTML5 Elements
  • Initial seed code should match the previous challenge (add h1, change p text)
• Fill in the Blank with Placeholder Text
  • Carry the main tag from previous exercise (this applies to every challenge after this one)
• Add Images to your Website
  • Remove CSS (won’t affect tests or instructions)
  • Move this challenge so it’s after Delete HTML Elements challenge
• Uncomment HTML
  • Paragraph text should carry Kitty Ipsum change from prior challenges
• Comment out HTML
  • Paragraph text should carry Kitty Ipsum change from prior challenges
• Delete HTML Elements
  • Move Add Images challenge after this one
• Link to External Pages with Anchor Elements
  • Remove CSS (won’t affect tests or instructions)
• Link to Internal Sections of a Page with Anchor Elements
  • Remove CSS (won’t affect tests or instructions)
• Nest an Anchor Element within a Paragraph

  • Remove CSS (won’t affect tests or instructions)
• Check Radio Buttons and Checkboxes by Default
  • Remove CSS (won’t affect tests or instructions)
• Nest Many Elements within a Single Div Element
  • Remove sentence in challenge copy about CSS (this will impact translations)
  • Remove CSS (won’t affect tests or instructions)
• Declare the Doctype of an HTML Document
• Define the Head and Body of an HTML Document

I removed link tags, everything in the style tags, and references to classes on elements when I ran through the challenges on Beta - one very good thing is it doesn’t change any of the instructions for the challenges, and the tests still worked. These changes should have minimal impact on the translations.

@raisedadead @Greenheart So will there be nothing to delineate the intro from the instructions? I think there should be something, at the very least maybe an unassuming <hr>

Which might look a little something like this:

Nightmode looks totally badass 😈 ! I think this works, what about you guys?

@QuincyLarson sounds like a plan! I’m working on this PR now, and will get the hr into the Basic HTML section.

@no-stack-dub-sack - I know you’re working on the Basic Data Structures section, that’s all yours 😄

After that, we could either have one person go through and make this fix everywhere, or split up the task into certificate sections, or topic sections. If we split it up, it probably makes sense to open a separate issue to track progress.
