Cascading sytle sheets or Css for short, was created to seperate content from sytle.So all the content, the stuff you read,go into your html files,all information about sytles go into your css file.
in css, every web page element generates a rectangular box. in order to use css for layout, you need to understand the basic properties of the css box
boxes can have position hieght padding borders and margins.
to allow text to wrap around a image, use the float property. this property makes the image into sort of an island, with text and other elements flowing around it (like water)
elements float with respect to the elements that follow them. there is no effect on the proceding (coming before) elements.
