我正在处理我正在构建的网站的注册表单,但不能将回显的错误消息与表单中的文本框分开。 每次我在浏览器中运行它来测试错误消息时,文本框都会向左移动(不对齐),错误消息显示在它们的右侧。显然,它对齐了中心的两个对象,但我只希望表单字段居中。感谢您提供的任何帮助。
这是我的html和css代码......
<!DOCTYPE html>

.form-group {

答案 0 :(得分:0)
一种方法是制作form-group
&#39; display:inline-block
和position:relative
。之后,您必须将form-group
与[{1}} text-align:center
放在form
上。
现在,您可以简单地将错误消息置于绝对位置并移动它们top:0;
和left: 270px
(250px输入宽度和2 * 10px填充)
如果您只想在输入框下输入错误消息,diplay:block; text-align:center;
上的简单help-block
就足够了
