https://www.templatemonster.com/blog/responsive-css3-form-fields-tutorial . 我的网站上使用此表单的页面是 https://maxstechandmathsite.azurewebsites.net/Registration . 如果你看看,你会清楚地看到一些造型问题。首先,我将向您展示HTML和CSS的重要部分:

HTML格式:

<div id="wrapper">
<form runat="server" onsubmit="return false">
<h1>Personal Information</h1>
<span style="float: right; font-size: 1.5em"><span class="red">*</span>&nbsp;Required</span>
<div class="col-4">
<label>
  Date of Birth (DOB) <span class="red">*</span>
<input type="date" required="required" placeholder="When is your date of birth?" id="dob" name="dob" tabindex="10" />
</label>
</div>
<div class="col-4">
  <label>
    Gender <span class="red">*</span>
    <select id="gender" required="required" name="gender" tabindex="11">
      <option>Male</option>
      <option>Female</option>
      <option>I do not wish to identify</option>
    </select>
  </label>
</div>
<div class="col-4 switch">
  <label>Send Text Notifications?</label>
  <center style="position:relative; padding-bottom: 8px"><input type="checkbox" class="js-switch" /></center>
</div>
<div class="col-4 switch">
  <label>Email Updates?</label>
  <center style="position:relative; padding-bottom: 8px"><input type="checkbox" class="js-switch" /></center>
</div>
<div id="BottomSection">
<br />
<h1 style="background-color: blueviolet">Login Information</h1>
<asp:CreateUserWizard ID="RegisterUser" runat="server" BackColor="#F7F7DE" BorderColor="#CCCC99" BorderStyle="Solid" BorderWidth="1px" Font-Names="Verdana" Font-Size="10pt" OnCreatedUser="CreateUserWizard1_CreatedUser">
</asp:CreateUserWizard>
<div style="text-align: center; font-size: 1.5em">
    Enter password hint for future reference:
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <br />
    <asp:CheckBox ID="CheckBox1" runat="server" />I have read and agree to the <asp:HyperLink ID="HyperLink2" runat="server" NavigateUrl="~/PrivacyPolicy.html">Privacy Policy</asp:HyperLink> &nbsp;and <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="~/TermsOfService.html">Terms Of Service</asp:HyperLink>.</div>
<div class="col-submit">
<button class="submitbtn">Submit Form</button>
</div>
</div>
</form>
</div>

CSS:

form > div.switch > label {
   padding: 22px 20px 18px;
}

label > input {
   display: inline-block;
   position: relative;
   width: 100%;
   height: 27px;
   line-height: 27px;
   margin: 5px -5px 0;
   padding: 7px 5px 3px;
   border: none;
   outline: none;
   color: #555;
   font-family: 'Helvetica Neue', Arial, sans-serif;
   font-weight: bold;
   font-size: 14px;
   opacity: .6;
   transition: all linear .3s;
}

label > select {
   display: block;
   width: 100%;
   padding: 7px 5px 3px;
   margin: 5px -5px 0;
   color: #555;
   font-weight: 500;
   height: 35px;
   border: none;
   outline: none;
   font-family: 'Helvetica Neue', Arial, sans-serif;
   font-size: 14px;
   opacity: .6;
   transition: all linear .3s;
}

h1

2) 对于最下面一行,显然有一些关于间距和边界的问题。出现蓝色边框,但它比上面行上的蓝色边框更厚,同时还有一些空白,并且底部行中每个列的高度和填充都不均匀。我试过调整和试验许多不同的 padding 和 margin 值,但保持不平衡。最后,我还断线了( <br>

如有帮助,不胜感激。谢谢!

1) 删除 font-size: 0 从 form

form {
  display: block;
  margin: 30px;
  overflow: hidden;
  background: #fff;
  border: 3px solid #7eaf4a;
  border-radius: 5px;
  font-size: 0;         /* <- remove this */
}

.col-3, .col-4 选择器 vertical-align: top 还有一个 min-height 为了让他们都有同样的高度和风格。

.col-3, .col-4 { 
  border-bottom: 3px solid #0026ff;
  border-right: 3px solid #0026ff;
  background-color: #ebf442;
  vertical-align: top;
  min-height: 100px;
}

我更新了一点 <span>Required</span> 元素和媒体查询,以使响应式设计正常工作,并包含上述修复。
