How do I make something visible when clicking something else in HTML?

For example, I have the HTML code %26lt;span id="hello" style="visibility:hidden"%26gt; Hello %26lt;/span%26gt; What code would I put around the other phrase "Say hello!" to make it so that when "Say hello!" is clicked, the word Hello becomes visible?

You need to use Javascript for that:





function ShowSpan()


{


var helloSpan = document.getElementById("hello");





if(helloSpan != null)


{


helloSpan.style = "display:block";


}


}





And in the click event of the button you need to specify the function name something like this:





onClick = "javascript:ShowSpan();"
Reply:You couldn't do it in html, you would have to use javascript or load a whole new page, which I don't think is what you want.
