Member Function Documentation

set_pseudo_element()

void css_class::set_pseudo_element	(	pseudo_element_type	pe,
		const css &	val,
		const std::string &	descendant = ""
	)

defines the value of a given pseudo-element

Note

same behavior of set_selector() above, but for pseudo-elements instead of pseudo-classes

set_selector()

void css_class::set_selector	(	selector_type	sel,
		const css &	ref,
		const std::string &	descendant = ""
	)

defines the value for a given css_selector on that class (or pseudo-class in CSS parlance)

Parameters

[in]	sel	the selector to be defined
[in]	ref	the css definition to give to that selector (= pseudo-class)
[in]	descendant	not an empty string, the definition applies to the specified descendant components (html type, like "p" for paragraph, "div" or other) or subcomponent with the provided class name.

Note

a descendant component is any component specified inside the current component, for example in the following html string "<div> demo <p> something </p> something else</div>" "<p>" is a descendant of "<div>". If one wants a specific css definition for "<p>" inside "<div>", the descendant string here should be "p" and the current css_class object be used (or rather referred by its name) by an html_div component. if the descendant is to be a class name rather than an HTML component name, it should be preceeded by a dot like ".myclassname". combining HTML component name with class is possible: "p.myclassname" and restricts the css definition to only "<p>" descendant having the "class=myclassname" attributes.
