There are many elements that you can use on parts of your text inside a paragraph, for example, you can make a word appear italicized by using the emphasis element. These elements are inside a block element, and so are known collectively as "inline elements".

You can also insert special characters, such as symbols like @ and ©. Technically, these are not inline elements, but they are similar as you can include them inside a block element such as a para.

To find out about some of the common inline elements, see:
