If you want a “editable grid” i.e. a table like structure that allows you to make any of the rows a form, use CSS that mimics the TABLE tag’s layout: display:table, display:table-row, and display:table-cell. There is no need to wrap your whole table in a form and no need to create a separate form and … Read more
Yes. They are not presentational elements — blockquote represents a block quotation, q represents an inline quotation, and cite represents a reference to a name, work, standard, URL, etc. You do have some validation errors that are fairly common with blockquote. A blockquote element cannot be inside a paragraph, and in HTML4 actually needs to … Read more
Explicitly Target IE versions without hacks using HTML and CSS Use this approach if you don’t want hacks in your CSS. Add a browser-unique class to the <html> element so you can select based on browser later.

While other answers are technically correct, they omit the fact that SVG provides an alternative mechanism for data-*. SVG allows any attribute and tag to be included, as long as it doesn’t conflict with existing ones (in other words: you should use namespaces).
