Bootstrap 5布局水平形式标签的大小

Bootstrap 5 Layout Horizontal form label sizing用于设置不同尺寸的表单输入栏的标签。要设置标签尺寸，请使用.col-form-label-sm或.col-form-label-lg类来<label>或<legend>标签的尺寸为.form-control-lg和.form-control-sm。

水平形式的标签尺寸使用类：

.col-form-label-sm:该类用于设置表单标签的大小为小。
.col-form-label-lg:该类用于设置表单标签的大小为大。
.form-control-sm:该类用于设置表单控件的大小为小。
.form-control-lg:该类用于设置表单控件的大小为大。

语法:

<div class="row">
      <label for="" class="col-form-label 
          col-form-label-sm"></label>
      <div class="col-*-*">
        <input type="email" 
            class="form-control form-control-sm" 
            id="" placeholder="">
      </div>
</div>
