CSS中文本框的排版非常重要，其中最基本的問題是對齊。對齊不好會影響整體美觀，影響用戶體驗。今天我們來學習如何將文本框的文本向上對齊。

首先，用HTML的標簽來創建一個文本框：</p><pre><code><textarea>這里是文本框</textarea></code></pre><p>接下來，我們為textarea添加CSS樣式：</p><pre><code>textarea{ vertical-align: top; }</code></pre><p>在這里，我們使用vertical-align屬性來實現向上對齊。該屬性有以下值：</p><ul><li>top：將元素的頂部與行中最高元素的頂部對齊（默認值）</li><li>middle：將元素的垂直中心與行中所在元素的基線對齊</li><li>bottom：將元素的底部與行中最低元素的底部對齊</li><li>baseline：將元素的基線與行中所在元素的基線對齊</li><li>sub：將元素的基線與下標基線對齊</li><li>super：將元素的基線與上標基線對齊</li><li>text-top：將元素的頂部與parent元素中第一行的字母的頂部對齊</li><li>text-bottom：將元素的底部與parent元素中最后一行的字母的底部對齊</li></ul><p>然后，我們可以看到文本框的文本已經向上對齊了。</p><p>這種方法對大多數瀏覽器都有效，但有些瀏覽器可能會出現難以預料的結果。如果你需要更高級的排版，那么建議使用CSS的強大樣式功能。</p></div><div
