HTML only includes very basic generated content, but CSS provides a much richer array of properties to specify generated content. It should be noted that for the purposes of first line and first letter, before is assumed to be the start of the element.
Subsequent elements consider generated content to be part of the element.
The dog sat on the log. Any other value for display will be reset to block . Inline elements may only have display set to none or inline , with other values reset to inline . Although we have already seen that CSS can generate content that is always the same, it also provides the ability for counter functions. Essentially these are the same as list items except they allow for more advanced numbering schemes.
