@daniel thank you for showing me the possibilities

javascript:(()=>{sp=String.fromCharCode(32);mn=document.querySelector("p:nth-child(4)");nl=document.createElement("p");nl.textContent="NAME:";ins=document.createElement("input");mn.appendChild(nl);mn.appendChild(ins);b=document.createElement("button");b.textContent="Enter";b.onclick=()=>{alert("hi"+sp+document.querySelector("input").value)};mn.appendChild(b);})() Testing
