Link Targets
The target attribute of the <a> element controls where the linked document opens. The most common values are _self (default — same tab) and _blank (new tab or window).
Security with target="_blank"
When you open a link in a new tab with target="_blank", the new page can access the opening page via window.opener. Always add rel="noopener noreferrer" to prevent this security vulnerability. noopener blocks access to window.opener and noreferrer additionally hides the referrer header.
