Difference between a <div> and <span> HTML tag
The primary difference between a div and a span is their default behavior. By default, a <div> is a block-level-element and a <span> is an inline element. In other words, if you want to adjust a small portion of text and not break it out of the current line, you should use a <span>. If you need to modify a large division, the height, move an element, or contain other elements, you should use a <div>.
