What I did today.(Freee Friday 4/26)

Today I learned some Javascript and practiced changing text when a button was clicked and also opening windows.

<script>
function changetext() {
    document.getElementById("head").innerHTML = "<h1>Ich bin sehr eingebildet -Ace</h1>"
}
function changetext2(){
    document.getElementById("head").innerHTML = "<h2>Ich bin nicht eingebildet -Ace</h2>"
}
function clickme() {
        Window:open("https://www.youtube.com/watch?v=dQw4w9WgXcQ")
}
function buymethings() {
    window:open("https://www.patreon.com/Aceofspadesprogrammer")
}

This is the code I wrote today.
