CSS Classes and Styles
CSS (Cascading Style Sheets) is a style sheet language used to describe the presentation of a (HTML) document. It is an important part of ZK to customize component's look and feel. If you are not familiar with CSS, please refer to CSS Tutorial.
There are a set of methods that could be used to set CSS styles for an individual component.
- HtmlBasedComponent.setStyle(String) assigns CSS styles directly to a component
- HtmlBasedComponent.setSclass(String) (i.e., sclass) assigns one or multiple CSS style classes to a component.
- HtmlBasedComponent.setZclass(String) (i.e., zclass) assigns the main CSS style class to a component. Unlike style and sclass, if zclass is changed, all default CSS styles won't be applied.
- Some components have a so-called content area and they have a separated set of methods to change the CSS style of the content area, such as Window.setContentStyle(String) and Window.setContentSclass(String).
