填充在文本字段中溢出容器

Question

我尝试将填充分配给文本字段，但右侧覆盖主要内容。我该如何解决？

     <div class='contenedor_section'>
      <input type='text' placeholder='name' class='estilo_input_text'>
     </div>


    .contenedor_section{
      padding: 20px;
      background:red;
    }
    .estilo_input_text {
        display: block;
        width: 100%;
        height: 34px;
        padding: 6px 12px;
        font-size: 14px;
        line-height: 1.42857143;
        color: #555;
        background-color: #fff;
        border: 1px solid #ccc;
        border-radius: 4px;
        -webkit-box-shadow: inset 0 1px 1px rgba(0,0,0,.075);
        box-shadow: inset 0 1px 1px rgba(0,0,0,.075);
        -webkit-transition: border-color ease-in-out .15s,box-shadow ease-in-out .15s;
        transition: border-color ease-in-out .15s,box-shadow ease-in-out .15s;
    }

    ::-webkit-input-placeholder { /* Chrome/Opera/Safari */
      font-style: italic;
      color: #999999 !important;
    }

Answer 1

将box-sizing: border-box;添加到.estilo_input_text。这包括宽度/高度设置中的填充和边框。

Answer 2

取消您应用的填充。或使用边框。 calc函数非常方便，并得到广泛支持，请使用它！

.contenedor_section{
  padding: 20px;
  background:red;
}
.estilo_input_text {
    display: block;
    width: calc(100% - 24px);/* you have to negate the padding of 12px on each side */
    height: 34px;
    padding: 6px 12px;
    font-size: 14px;
    line-height: 1.42857143;
    color: #555;
    background-color: #fff;
    border: 1px solid #ccc;
    border-radius: 4px;
    -webkit-box-shadow: inset 0 1px 1px rgba(0,0,0,.075);
    box-shadow: inset 0 1px 1px rgba(0,0,0,.075);
    -webkit-transition: border-color ease-in-out .15s,box-shadow ease-in-out .15s;
    transition: border-color ease-in-out .15s,box-shadow ease-in-out .15s;
}

::-webkit-input-placeholder { /* Chrome/Opera/Safari */
  font-style: italic;
  color: #999999 !important;
}

  <div class='contenedor_section'>
    <input type='text' placeholder='name' class='estilo_input_text'>
  </div>

解决方案：将width: calc(100% - 24px);添加到.estilo_input_text：

.estilo_input_text {
    width: calc(100% - 24px);

}

.estilo_input_text {
    display: block;
    width: calc(100% - 24px);
    height: 34px;
    padding: 6px 12px;
    font-size: 14px;
    line-height: 1.42857143;
    color: #555;
    background-color: #fff;
    border: 1px solid #ccc;
    border-radius: 4px;
    -webkit-box-shadow: inset 0 1px 1px rgba(0,0,0,.075);
    box-shadow: inset 0 1px 1px rgba(0,0,0,.075);
    -webkit-transition: border-color ease-in-out .15s,box-shadow ease-in-out .15s;
    transition: border-color ease-in-out .15s,box-shadow ease-in-out .15s;
}

::-webkit-input-placeholder { /* Chrome/Opera/Safari */
  font-style: italic;
  color: #999999 !important;
}

  <div class='contenedor_section'>
    <input type='text' placeholder='name' class='estilo_input_text'>
  </div>
