Pagination

<nav class="pagination" aria-label="Pages"><a rel="prev" aria-label="Previous" href="/docs/pagination?page=42"><</a><a href="/docs/pagination">1</a><a role="separator" aria-disabled="true">…</a><a href="/docs/pagination?page=42">42</a><a role="link" aria-disabled="true" aria-current="page">43</a><a href="/docs/pagination?page=44">44</a><a role="separator" aria-disabled="true">…</a><a href="/docs/pagination?page=50">50</a><a rel="next" aria-label="Next" href="/docs/pagination?page=44">></a></nav>
