How to get the cursor to change to the hand when hovering a <button> tag

see: https://developer.mozilla.org/en-US/docs/Web/CSS/cursor

so you need to add: cursor:pointer;

In your case use:

#more {
  background:none;
  border:none;
  color:#FFF;
  font-family:Verdana, Geneva, sans-serif;
  cursor:pointer;
}

This will apply the curser to the element with the ID "more" (can be only used once). So in your HTML use

<input type="button" id="more" />

If you want to apply this to more than one button then you have more than one possibility:

using CLASS

.more {
  background:none;
  border:none;
  color:#FFF;
  font-family:Verdana, Geneva, sans-serif;
  cursor:pointer;
}

and in your HTML use

<input type="button" class="more" value="first" />
<input type="button" class="more" value="second" />

or apply to a html context:

input[type=button] {
  background:none;
  border:none;
  color:#FFF;
  font-family:Verdana, Geneva, sans-serif;
  cursor:pointer;
}

and in your HTML use

<input type="button" value="first" />
<input type="button" value="second" />

Just add this style:

cursor: pointer;

The reason it's not happening by default is because most browsers reserve the pointer for links only (and maybe a couple other things I'm forgetting, but typically not <button>s).

More on the cursor property: https://developer.mozilla.org/en/CSS/cursor

I usually apply this to <button> and <label> by default.

NOTE: I just caught this:

the button tags have an id of #more

It's very important that each element has it's own unique id, you cannot have duplicates. Use the class attribute instead, and change your selector from #more to .more. This is actually quite a common mistake that is the cause of many problems and questions asked here. The earlier you learn how to use id, the better.

All u need is just use one of the attribute of CSS , which is---->

cursor:pointer

just use this property in css , no matter its inline or internal or external

for example(for inline css)

<form>
<input type="submit" style= "cursor:pointer" value="Button" name="Button">
</form>

 #more {
    background:none;
    border:none;
    color:#FFF;
    font-family:Verdana, Geneva, sans-serif;
    cursor: pointer;
}
