Focus element with HTML4.01 Strict, CSS 2.1, and JS 1.7

Question

I am trying to figure out if there is a way to auto-focus an input element on page load that is compatible with HTML 4.01 Strict, CSS 2.1, and JS 1.7, since the autofocus attribute is not available to HTML 4.01 and I do not believe the focus method is available in JS 1.7.

Is there a way to still accomplish this with those restrictions?

I think I may have found an answer to my question. According to this w3.org document, the focus method belongs to the DOM Level 1. Does this mean that the method is indeed available?

@JesusCarrasco i'm coding a website according the PS4 browser specifications. i think i may have found an answer to my question, nonetheless. according to this document, it would seem that the focus method is indeed part of DOM Level 1. — oldboy

@James yeah, i edited my question. i came across a w3.org document that says it belongs to DOM Level 1. i wasn't sure because i couldn't find anything about it until a few seconds ago — oldboy

According to this w3.org document, the focus method belongs to the DOM Level 1 so is available.

Try this code is javascript vanilla.

JAVASCRIPT

window.onload = function() {
   document.getElementById("Box1").focus();
};

HTML

<input type="text" id="Box1"/>
