attributes (id, class, src, alt) are separated by spaces, take a look at this:
<img src="image_url" alt="my image">
see how i have two attributes? The value runs from the first till second quotation mark (
") and separated by a space, the separation by semi-colon is when you use the style attribute which can have multiply values:
<p style="color: red; font-size: 16px">
