Whats the difference between <blockquote> and <q> tags?

You can use the q tag for short inline quotations like so:

<q>This is a pull quote from the book of...</q>

You can use a blockquote tag for marking up long, multi-line quotations. For instance, if you're writing a blog post where you quote an excerpt from a book, article, or another source, you should wrap that quote inside blockquote tags.

<blockquote>
   In the sky there are always answers and explanations for everything: every pain, every suffering, joy and confusion.”...
</blockquote>

Inside the opening blockquote tag you can optionally use the cite attribute to include a reference to the text you're quoting. So as the value, you include the link to the source of the quote.

<blockquote cite="https://www.goodreads.com/quotes/tag/long"> In the sky there are always answers and explanations for everything: every pain, every suffering, joy and confusion.”... </blockquote>

You can also credit the author of the quote using cite tags within the blockquote.

<blockquote> In the sky there are always answers and explanations for everything: every pain, every suffering, joy and confusion.”.... - <cite><a href="https://www.goodreads.com/quotes/tag/long">Author Name</a></cite> </blockquote>

Finally, in a blockquote, it's also acceptable to attribute the author or source within a footer element.

<blockquote>
    In the sky there are always answers and explanations for everything: every pain, every suffering, joy and confusion.”.... 
    <footer>
         - <cite><a href="https://www.goodreads.com/quotes/tag/long">
        Author Name</a></cite>
    </footer>
</blockquote>

In short, use q tags for short inline quotations and use blockquotes for marking up long/multi-line quotations.
