#Basic Components
The framework provides developers with a set of basic components that can be combined to achieve quick development. For more information, see Component Documentation.
What is component?
- A component is the basic building block of a view layer.
- A component comes with some features and Weixin styles.
- A component includes a
start tag,end tag,property(modifies the component), andcontent(between the two tags).
<tagname property="value">

Note: All components and properties are in lowercase and joined with a hyphen -.
