1、background-color即背景色,当我们设置成red,如图<body style="background-color:red">背景this is background</body>

3、换成段落p呢?<p style="background-color:green">段落This is a paragraph.</p>

5、font-family字体,h1的字体为宋体,如图<h1 style="font-family:'宋体'">heading h1</h1>

7、设置文本居中,以h1为例,效果如下<h1 style="text-align:center">heading h1</h1>
