targetblank

Targetblank refers to the HTML behavior of opening a linked document in a new browsing context, typically a new tab or window. It is implemented using the anchor element with the target attribute set to "_blank" (for example, <a href="https://example.com" target="_blank">Example</a>). This approach is commonly used for external links or resources intended to keep the original page accessible.

Security considerations are central to target="_blank" usage. When a link opens in a new tab, the newly opened page can access the original page via window.opener, creating potential security and performance risks. To mitigate this, it is standard practice to include a rel attribute such as rel="noopener" or rel="noopener noreferrer" in combination with target="_blank". This severs the connection between the two pages and prevents the new page from manipulating the original.

Accessibility considerations apply to target="_blank" as well. Because opening a link in a new tab can be surprising to some users, many guidelines recommend informing users when a link will open in a new tab. This can be done with explicit link text, a visible or accessible label, or by adding aria-label attributes that indicate the behavior for assistive technologies.

Best practices for use include reserving target="_blank" for links that navigate away from the current content, such as external sites or documents, rather than for primary in-page navigation. When used, developers should ensure that the purpose is clear, provide a reliable visual cue, and implement appropriate security via rel="noopener" or rel="noreferrer".

Browser support for target="_blank" is extensive across modern engines, making it a widely compatible method for controlling link behavior.
