Get revamped page html and css to validate

[jsheunis]

https://validator.w3.org/nu/

Summary:

• 58 validation errors/warnings
• Bad value https://matrix.to/#/#datalad:matrix.org for attribute href on element a: Illegal character in fragment: # is not allowed. ==> not sure if we can do anything about this
• The frameborder attribute on the iframe element is obsolete. Use CSS instead. ==> fixed
• No p element in scope but a p end tag seen. ==> validator seems to be wrong, or some syntax issue is causing it to see this as a problem, where it isn't (there is a p element)
• All other validation errors/warnings (~52) related to VueJS directives / tags 🙃

Index page validates now. Vue still shits all over the "in the wild" page.

Closing, since everything validates except for vue 🙃
