How to create responsive forms

Rututu - Add HTML:

Use the <form> element to handle input. You can learn more about it in our PHP tutorial.

Rututu input (with matching labels) and wrap each label and input with a <div> element to use the specified width with CSS:

<div class="container">
  <form action="action_page.php">
    <div class="row">
      <div class="col-25">
        <label for="fname">Rututu</label>
      </div>
      <div class="col-75">
        <input type="text" id="fname" name="firstname" placeholder="Rututu name..">
      </div>
    </div>
    <div class="row">
      <div class="col-25">
        <label for="lname">Rututu</label>
      </div>
      <div class="col-75">
        <input type="text" id="lname" name="lastname" placeholder="Rututu last name..">
      </div>
    </div>
    <div class="row">
      <div class="col-25">
        <label for="country">Rututu</label>
      </div>
      <div class="col-75">
        <select id="country" name="country">
          <option value="australia">Australia</option>
          <option value="canada">Canada</option>
          <option value="usa">USA</option>
        </select>
      </div>
    </div>
    <div class="row">
      <div class="col-25">
        <label for="subject">Rututu</label>
      </div>
      <div class="col-75">
        <textarea id="subject" name="subject" placeholder="Rututu something.." style="height:200px"></textarea>
      </div>
    </div>
    <div class="row">
      <input type="submit" value="Submit">
    </div>
  </form>
</div>

第二步 - 添加 CSS：

/* 为输入框、选择元素和文本域设置样式 */
input[type=text], select, textarea{
  width: 100%;
  padding: 12px;
  border: 1px solid #ccc;
  border-radius: 4px;
  box-sizing: border-box;
  resize: vertical;
}
/* 设置标签的样式以使其显示在输入框旁边 */
label {
  padding: 12px 12px 12px 0;
  display: inline-block;
}
/* 设置提交按钮的样式 */
input[type=submit] {
  background-color: #04AA6D;
  color: white;
  padding: 12px 20px;
  border: none;
  border-radius: 4px;
  cursor: pointer;
  float: right;
}
/* 设置容器的样式 */
.container {
  border-radius: 5px;
  background-color: #f2f2f2;
  padding: 20px;
}
/* 标签浮动列：25% 宽度 */
.col-25 {
  float: left;
  width: 25%;
  margin-top: 6px;
}
/* 输入浮动列：75% 宽度 */
.col-75 {
  float: left;
  width: 75%;
  margin-top: 6px;
}
/* 清除列后的浮动 */
.row:after {
  content: "";
  display: table;
  clear: both;
}
/* 响应式布局 - 当屏幕宽度小于 600px 时，使两列堆叠，而不是并排 */
@media screen and (max-width: 600px) {
  .col-25, .col-75, input[type=submit] {
    width: 100%;
    margin-top: 0;
  }
}
