回顧：Bootstrap的手腳架(Scaffolding)提供了固定(fixed)和流式(fluid)兩種布局，它同時建立了一個寬達940px和12列的格網(wǎng)系統(tǒng)。
? ? ? 基于手腳架(Scaffolding)之上，Bootstrap的基礎(chǔ)CSS(Base CSS)提供了一系列的基礎(chǔ)Html頁面要素，旨在為用戶提供新鮮、一致的頁面外觀和感覺。本文將主要深入講解排版(Typography),表格(Table),表單(Forms),按鈕(Buttons)這四個方面的內(nèi)容。
-
排版 (Typography)
，它囊括標(biāo)題(Headings),段落 (paragraphs), 列表(lists)以及其他內(nèi)聯(lián)要素。我們可以通過修改variables.less的兩個變量:
@baseFontSize?和?@baseLineHeight來控制整體排版的樣式。Bootstrap同時還用了一些其他的算術(shù)方法來創(chuàng)建所有類型要素的margin,padding,line-height等。
? ? ? ? 1.1 ? 標(biāo)題和段落使用常見的html<h*></h*>和<p></P>即可表現(xiàn),可以不必考慮margin,padding。兩者顯示效果如圖2-1所示：
? ? ? ? ?
圖2-1 標(biāo)題與段落(Headings¶graphs)
? ? ? 1.2 ?強調(diào)(Emphasis).使用<strong>和<em>兩個標(biāo)簽，前者使用粗體，后者使用斜體來強調(diào)標(biāo)簽內(nèi)容。請注意<strong>標(biāo)簽在html4中定義語氣更重的強調(diào)文本；在 HTML 5 中，<strong> 定義重要的文本。這些短語標(biāo)簽也可以通過定義CSS的方式來豐富效果。更多短語標(biāo)簽請參見[1].縮寫(abbreviations?).使用<abbr>，它重新封裝了該標(biāo)簽，鼠標(biāo)滑過會異步地顯示縮寫的含義。引入title屬性來顯示原文，使用.initialism類對縮寫以大寫方式顯示。
? ? ? 1.3 ?引用文字(Blockquotes).使用<blockquote>標(biāo)簽和<small>兩個標(biāo)簽，前者<blockquote>是引用的文字內(nèi)容，后者<small>是可選的要素，能夠添加書寫式的引用，比如內(nèi)容作者。如圖2-2所示

? ? 1.4列表(lists).Bootstrap提供三種標(biāo)簽來表現(xiàn)不同類型的列表。<ul>表示無序列表，<ul class="unstyled">表示無樣式的無序列表，<ol>表示有序列表，<dl>表示描述列表，<dl class="dl-horizontal">表示豎排描述列表。圖2-3較好顯示了這幾種列表：
圖2-3 列表(lists)
? ? 2.表格(Table).依然使用<table><tr><th><td>等標(biāo)簽來表現(xiàn)表格。主要提供了四個css的類來控制表格的邊和結(jié)構(gòu)。表2-1顯示了bootstrap的table可選項。

?
? ?3. ?表單(Forms).Bootstrap的表單是非常驚艷的部分。最好的地方在于你如何使用這些hmtl標(biāo)簽，它都會有很好的表現(xiàn)效果，而且不需要其他多余的代碼。無論多復(fù)雜的布局都可以根據(jù)這些簡潔，可擴展，事件綁定的要素來輕易實現(xiàn)。主要提供了四四種表單選項，如表2-2所示：

|
Horizontal
|
.form-horizontal
|
左漂浮, 右對齊標(biāo)簽?

? ? ? ? ?推薦到官方文檔去體驗下各種表單要素的真實效果，在chrome,Firefox等現(xiàn)代瀏覽器下顯示十分優(yōu)雅。同時可以使用.control-group來控制表單輸入、錯誤等狀態(tài)，需要wekit內(nèi)核。如圖2-5所示：

? ? 4.按鈕(Buttons).Bootstrap提供多種樣式的按鈕，同樣是通過CSS的類來控制,包括btn, btn-primary,?btn-info,btn-success等不同顏色的按鈕，亦可以簡單通過.btn-large?.btn-mini等CSS的class控制按鈕大小，能夠同時用在<a>,<button>,<input>標(biāo)簽上，非常簡單易用。如圖2-6所示，不同顏色的按鈕：
