<a target="\_blank">

About that, you should add rel="noopener" (and maybe noreferer too) there, or the linked site could inject JS in yours, a security risk for your visitors.

I have a little usercss that adds a warning picture (::after { content: "pic"; }) on _target without noopener and especially Github is bad there.

Can you share some reference? I don't understand how some linked site could affect the site containing it.

Stackoverflow, but here you go.

I've made a userscript that puts a rel="noopener" on target="_blank" links where missing, with no issues for about half a year usage. While noreferer breaks some payment processors and the like. Sadly i lost it a few months ago, need to redo it sometime.
