使用flexbox进行输入字段换行 [英] Input field wrapping using flexbox

问题描述

我是Flexbox的新手，我试图创建一个输入表单，如下图所示.首先，假定两个字段为div宽度的50％，另两个字段为100％宽度.在移动视图中，它们应该相互堆叠.我可以使用宽度"和高度"textarea上的属性?

I'm new to the flexbox, and I tried to create an input form like in the picture below. First, two fields are supposed to be 50% of the width of div, other two are 100% width. In the mobile view, they are supposed to stack on each other. Can I use "width" and "height" attributes on textarea?

.form{
  display: flex;
  flex-wrap: wrap;
  text-align: center;
  justify-content: center;
  align-items: center;
  width: 100%;
}

.input-flex{
  max-width: 600px;

}

input, textarea{
  border: 0;
  border-radius: 6px;
  padding: 2%;
  background-color: darkgray;
  margin-right: 5%;
  margin-bottom: 5%;
  flex:1 0 100%;
}

<div class="form">
  <div class="input-flex">
    <input type="text" name="name" placeholder="Name*"/>       
    <input type="email" name="email" placeholder="E-mail*"/>
    <input type="tel" name="number" placeholder="Phone number*"/>
    <textarea cols="55" rows="15" placeholder="Questions"></textarea>
  </div>  
</div>

推荐答案

请注意，即使元素位于 .input-flex -所以我只是将样式复制到了此元素.

Please note that you defined .form as the flex parent, even though your elements were inside .input-flex - so I just copied the style to this element.

关于您的问题:通过使用专用的类，您可以指定哪些元素应具有100％的宽度.

Regarding your question: by using a dedicated class, you can specify which elements should have 100% width.

除此之外，我将 margin 更改为在元素周围保持不变，因此结果与设计更好地匹配.

Other than that, I changed the margin to be constant all around the elements, so the result better matches the design.

.form {
  width: 100%;
}

.input-flex {
  max-width: 600px;
  display: flex;
  flex-wrap: wrap;
  text-align: center;
  justify-content: center;
  align-items: center;
}

input,
textarea {
  border: 0;
  border-radius: 6px;
  padding: 2%;
  background-color: darkgray;
  margin: 10px;
  box-sizing: border-box;
  flex-grow: 1;
}

.full-width {
  width: 100%;
}

<div class="form">
  <div class="input-flex">
    <input type="text" name="name" placeholder="Name*" />
    <input type="email" name="email" placeholder="E-mail*" />
    <input type="tel" class="full-width" name="number" placeholder="Phone number*" />
    <textarea cols="55" rows="15" class="full-width" placeholder="Questions"></textarea>
  </div>
</div>
