README.md

Add a target=_blank and rel=nooopener for all links to outside your page. Useful for security and accesibility

<script>
  Array.prototype.slice.call(document.querySelectorAll("a[href^=http]")).map((el)=> {
    el.setAttribute("target", "_blank");
    el.setAttribute("title", el.href);
    el.setAttribute("rel", "noopener");
  });
</script>

This will convert:

Here is <a href="https://mariocesar.xyz/">my site</a>

To

Here is <a href="https://mariocesar.xyz/" title="https://mariocesar.xyz/" target="_blank" rel="noopener">my site</a>
