如何美化網頁文字(10)-[text-align]置中、靠左、靠右


0000標題021
改變文章段落對齊,是文章中常用的方式,可以利用text-align 來做設定,他的屬性有 left、right、justify、center,分別為靠左、靠右、左右對齊、置中。
寫段html 吧!
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>魚和橙</title>
</head>
<body>
<h1>text-align</h1>
<p id="line1">The results of a survey <strong>keyword</strong> Friday showed <span>that 70 percent</span> of local <em>salaried employees</em> are hesitant(1) about getting married, citing insufficient(2) savings and job instability as the reasons.魚 橙</p>
<p id="line2">The results of a survey <strong>keyword</strong> Friday showed <span>that 70 percent</span> of local <em>salaried employees</em> are hesitant(1) about getting married, citing insufficient(2) savings and job instability as the reasons.魚 橙</p>
<p id="line3"> The results of a survey <strong>keyword</strong> Friday showed <span>that 70 percent</span> of local <em>salaried employees</em> are hesitant(1) about getting married, citing insufficient(2) savings and job instability as the reasons.魚 橙</p>
<p id="line4"> The results of a survey <strong>keyword</strong> Friday showed <span>that 70 percent</span> of local <em>salaried employees</em> are hesitant(1) about getting married, citing insufficient(2) savings and job instability as the reasons.魚 橙</p>
</body>
</html>

加入css吧!!
<style type="text/css">
#line1 {
    text-align: left;
    background-color: #F00;
}
#line2 {
    text-align: right;
    background-color: #999;
}
#line3 {
    text-align: center;
    background-color: #0F0;
}
#line4 {
    text-align: justify;
    background-color: #0FF;
}
</style>
看看結果吧!

前面兩行看不出結果,在最後一行,可以看到設定的結果,加入這樣的css就可改變對齊方式。
而使用 justify 他在用於列印程式(word 等 )是很適合使用的,而在網頁文字的使用上,他的使用效果並不是很明顯,所以通常僅使用left right center 的屬性。
而在正式使用上,文本對齊方向還是都用靠左(預設 ),所以此功能其實不多用,因為靠左靠右,有時候是用區塊來排版,較為常用。
