css颜色/字体/背景属性

背景属性

'''
background-color: cornflowerblue

background-image: url('1.jpg');

background-repeat: no-repeat;(repeat:平铺满)

background-position: right top(20px 20px);(横向:left center right)(纵向:top center bottom)

      简写:<body style="background: 20px 20px no-repeat #ff4 url('1.jpg')">

              <div style=" 300px;height: 300px;background: 20px 20px no-repeat #ff4 url('1.jpg')">
'''

注意:如果将背景属性加在body上,要记得给body加上一个height,否则结果异常,这是因为body为空,无法撑起背景图片;另外,如果此时要设置一个width=100px,你也看不出效果,除非你设置出html。
