如何用html css设置漂亮的页面,第1张

CSS是由选择器加声明组成的。

比如:

h1{color:red}

h1就是选择器,意思是只要遇到h1,就使用该CSS的规则

color:red:这个事声明

color:这个是属性

red:这个是值

OK,我们先来分析选择器。

1,打开记事本,并在其中输入必要信息,完整代码如下:

<!DOCTYPE html><html><head><meta charset="utf-8"><title></title>

<body><header><img src="molihua.jpg"width="412" height="291"</header><article><header><h2>茉莉花</h2><p>作者:宋 · 刘克庄 </p></header><hr/><p>曾与瑶姬约。恍相逢、翠裳摇曳,珠韝联络。风露青冥非人世,揽结玉龙骖鹤。

爱万朵、千条纤弱。

祷祝花神怜惜取,问开时、晴雨须斟酌。枝上雪,莫消却。

恼人匹似中狂药。

凭危栏、烛光交映,乐声遥作。身上春衫香薰透,看到参横月落。

算茉莉、犹低一著。坐有缑山王郎子,倚玉箫、度曲难为酢。君不饮,铸成错。</p><h3>清平乐</h3><p>冰轮万里。云卷天如洗。先向海山生大士。却诞卯金之子。冰盆荔子堪尝。胆瓶茉莉尤香。震旦人人炎热,补陀夜夜清凉。</p><dl><dt>《浣溪沙》</dt><dd>南国幽花比并香。直从初夏到秋凉</dd><dt>《鹧鸪天》</dt><dd>携靓侣,泛轻航。棹歌惊起野鸳鸯</dd><dt>《真珠帘》</dt><dd>茉莉芰荷香,拍满笙箫院。</dd>

</dl></article><footer>2019.9.6</footer></body></html>

启动浏览器运行后,大家会发现界面并不美观,文字看着也比较乱。

为了解决这个问题,可以在界面添加css规则,让界面更好看,更标准化,将下面的代码块添加到记事本中,位置在<head>和<head/>也就是头部之间:

<style type="text/css">body{ background:gray} h2{ text-align:center} header{ text-align:center} article p{ text-indent:2em} footer{ font-size:12pxfont-align:center} </style>

<style type="text/css">

body{ background:#fffpadding:0margin:0font-size:12px}

img{ border:0padding:0margin:0}

ul{list-style:none}

.login_bg{ background:url(<%=path%>financemanage/images/login_new/login_bg.gif) repeat-xheight:591px}

.dl_bg{ background:url(<%=path%>financemanage/images/login_new/dlbg.jpg) no-repeat center top}

.diwen{ background:url(<%=path%>financemanage/images/login_new/diwen.gif) repeat-x}

.usename{ font-size:14pxcolor:#0e3c00}

.dl_text{ width:145pxheight:17pxbackground:url(<%=path%>financemanage/images/login_new/text.gif) repeat-x centerborder:1px solid #1c5302}

.dl_but{ width:75pxheight:50pxbackground:url(<%=path%>financemanage/images/login_new/dlbut.gif) no-repeatborder:0 nonecursor:pointer}

</style>

<script language="javascript" type="text/javascript">

var count = 0

function submit_onclick(obj){

if (count == 0) {

//alert("MAC:" + document.forms[0].MACAddr.value)

obj.submit()

count ++

}

}

function submit2() {

if (count != 0) {

return false

}

if (event.keyCode==13) {

document.forms[0].submit()

}

}

</script>

<!-- script FOR="foo" EVENT="OnObjectReady(objObject,objAsyncContext)" LANGUAGE="JScript">

if(objObject.IPEnabled &&objObject.IPAddress(0) != null &&objObject.IPAddress(0) != "undefined")

IPAddr = objObject.IPAddress(0)

}

</script>
