bootstrap3 是否具有增加文本输入字段宽度的本机功能?
我知道在 bootstrap2 中我只是附加一个像 input-lg 这样的类来修改输入的宽度，但是在 bootstrap3 中这似乎只是增加了高度.
查看列大小调整"小节 此处.
使用 .input-lg 等类设置高度，使用 .col-lg-* 等网格列类设置宽度.
来自 Bootstrap 3 网站的示例:
<div class="col-lg-2"><input type="text" class="form-control" placeholder=".col-lg-2"><div class="col-lg-3"><input type="text" class="form-control" placeholder=".col-lg-3">
<div class="col-lg-4"><input type="text" class="form-control" placeholder=".col-lg-4">
Does bootstrap3 have native functionality for increasing the width of a text input field?
I know in bootstrap2 I'd just append a class like input-lg to modify the width of the input, however in bootstrap3 this just seems to increase the height.
Take a look at the "Column sizing" subsection here.
Example from Bootstrap 3 website:
<div class="row">
<div class="col-lg-2">
<input type="text" class="form-control" placeholder=".col-lg-2">
</div>
<div class="col-lg-3">
<input type="text" class="form-control" placeholder=".col-lg-3">
</div>
<div class="col-lg-4">
<input type="text" class="form-control" placeholder=".col-lg-4">
</div>
</div>
