如何使文本框随文字多少

要使文本框（Text Box）随文字多少自动调整大小，可以通过编程的方式来实现。以下是在几种常见编程语言中实现这一功能的示例：

HTML + CSS

在HTML中，你可以使用``元素来创建一个文本框，并通过CSS来控制其大小。 </p><p>```html </p><p><!DOCTYPE html> </p><p><html lang="en"> </p><p><head> </p><p><meta charset="UTF-8"> </p><p><meta name="viewport" content="width=device-width, initial-scale=1.0"> </p><p><style> </p><p> textarea { </p><p> width: 100%; / 使文本框宽度为父容器宽度 / </p><p> height: 50px; / 初始高度 / </p><p> resize: none; / 禁止用户手动调整大小 / </p><p> overflow: hidden; / 隐藏溢出的内容 / </p></div> </div> <div class="showall">-- 展开阅读全文 --</div> </div> <footer class="entry-footer"> <div class="readlist ds-reward-stl"> <div class="read_outer"><a
