This text appears in a div element that belongs to the 'para-style' class, which has its colours and font styles set by an external style sheet
This text also appears in a div element that belongs to the same class as the one before, so it shares the same styles
Like the two paragraphs above, this paragraph also belongs to the 'para-style' class, so uses that style. In addition, however, this text appears in a span element with a different syle, while the rest of the text is outside the span and reverts to the style applied to the div
Of course there is no reason why both divs and spans cannot belong to the same class. This div uses the same style as the span in the previous div, though it appears differently because unlike the example above it does not inherit the style of the surrounding block
