I could do the test, but didn't understand some things

Tell us what’s happening:
Hey everyone,

I don’t understand why using left: -10000
width: 1px and height 1px. Also didn’t understand the use of overflow property.
Your code so far

.sr-only {
  left: -10000px;
  top: auto;
  overflow: hidden;
      <li><a href="#stealth">Stealth &amp; Agility</a></li>
      <li><a href="#combat">Combat</a></li>
      <li><a href="#weapons">Weapons</a></li>
