What is the difference between <p> and <div>
Can they be used interchangeably I would say the second one, than the <p> is not inheriting attributes of <a> and keeping it's original formatting. Correct but some times you have to close it any way eg When you align the paragraph left/right/center
The <p> tag is a p aragraph, and as such, it is a block element (as is, for instance, h1 and div), whereas span is an inline element (as, for instance, b and a) block elements by default create some whitespace above and below themselves, and nothing can be aligned next to them, unless you set a float attribute to them Inline elements deal with spans of text inside a paragraph P and div elements are block level elements where span is an inline element and hence margin on span wont work Alternatively you can make your span a block level element by using css display
Or for span i would prefer display
