表单控件(Form controls)

所有通用的 表单控件, 旨在保持一致性

Bulma 支持如下 HTML内建表单元素: <form> <button> <input> <textarea> and <label>.

支持一下 CSS :

  • label
  • input
  • textarea
  • select
  • checkbox
  • radio
  • button
  • help

为了保持设计均匀平衡,Bulma 提供了一个非常有用的control容器,您可以在其中包装表单控件。
当在表单中组合多个控件时,请使用field类作为容器,以保持间距一致。

</div>

为了使用Bulma获得最佳效果,建议尽可能多地使用control元素


表单域(Form field) #

field 容器是一个简单的容器:

  • 文本标签 label
  • 表单控件 control
  • 可选文本 help

This is a help text

<div class="field">
  <label class="label">Label</label>
  <div class="control">
    <input class="input" type="text" placeholder="Text input">
  </div>
  <p class="help">This is a help text</p>
</div>

此容器允许表单字段有一致地间隔。

<div class="field">
  <label class="label">Name</label>
  <div class="control">
    <input class="input" type="text" placeholder="e.g Alex Smith">
  </div>
</div>

<div class="field">
  <label class="label">Email</label>
  <div class="control">
    <input class="input" type="email" placeholder="e.g. alexsmith@gmail.com">
  </div>
</div>

表单控件(Form control) #

Bulma control 是一种通用的 块(block) 容器,用于增强表单功能. 因为它与 控件元素具有相同的高度,所以它 只能包含 以下元素::

  • input
  • select
  • button
  • icon

该容器具有以下功能:

  • 保持间距一致
  • 将表单控件组合到一个组中
  • 将表单控件合并到列表中
  • 将图标追加和添加到表单控件
<div class="control">
  <input class="input" type="text" placeholder="Text input">
</div>
<div class="control">
  <div class="select">
    <select>
      <option>Select dropdown</option>
      <option>With options</option>
    </select>
  </div>
</div>
<div class="control">
  <button class="button is-primary">Submit</button>
</div>

使用图标(With icons) #

您可以在控件上附加如下2个修饰符之一:

  • has-icons-left
  • 和/或 has-icons-right

您还需要在图标上添加修饰符:

  • 如果使用 has-icons-left 需要添加icon is-left
  • 如果使用has-icons-right 需要添加icon is-right

图标容器的大小将由 input 容器定义。

<div class="field">
  <p class="control has-icons-left has-icons-right">
    <input class="input" type="email" placeholder="Email">
    <span class="icon is-small is-left">
      <i class="fas fa-envelope"></i>
    </span>
    <span class="icon is-small is-right">
      <i class="fas fa-check"></i>
    </span>
  </p>
</div>
<div class="field">
  <p class="control has-icons-left">
    <input class="input" type="password" placeholder="Password">
    <span class="icon is-small is-left">
      <i class="fas fa-lock"></i>
    </span>
  </p>
</div>
<div class="field">
  <p class="control">
    <button class="button is-success">
      Login
    </button>
  </p>
</div>

您也可以在 下拉框 中添加图标。

<div class="field">
  <p class="control has-icons-left">
    <span class="select">
      <select>
        <option selected>Country</option>
        <option>Select dropdown</option>
        <option>With options</option>
      </select>
    </span>
    <span class="icon is-small is-left">
      <i class="fas fa-globe"></i>
    </span>
  </p>
</div>

如果控件中包含图标,Bulma 将会确保图标保持 居中,不用担心 input 或 图标的大小。

<div class="field">
  <label class="label is-small">Small input</label>
  <div class="control has-icons-left has-icons-right">
    <input class="input is-small" type="email" placeholder="Normal">

    <span class="icon is-medium is-right">
      <i class="fas fa-check fa-lg"></i>
    </span>
  </div>
</div>

表单插件(Form addons) #

如果您要同时使用 附件控件,请在 field 容器上添加 has-addons 修饰符:

<div class="field has-addons">
  <div class="control">
    <input class="input" type="text" placeholder="Find a repository">
  </div>
  <div class="control">
    <a class="button is-info">
      Search
    </a>
  </div>
</div>

您 只能 在 inputs, buttons, and dropdowns 中使用追加

追加一个 静态按钮将会很有用。

<div class="field has-addons">
  <p class="control">
    <input class="input" type="text" placeholder="Your email">
  </p>
  <p class="control">
    <a class="button is-static">
      @gmail.com
    </a>
  </p>
</div>

使用 is-expanded 修饰符填充剩余的空间 (本例中, 是 input 元素):

Transfer

Transfer

<div class="field has-addons">
  <p class="control">
    <span class="select">
      <select>
        <option>$</option>
        <option>£</option>
        <option></option>
      </select>
    </span>
  </p>
  <p class="control">
    <input class="input" type="text" placeholder="Amount of money">
  </p>
  <p class="control">
    <a class="button">
      Transfer
    </a>
  </p>
</div>

<div class="field has-addons">
  <p class="control">
    <span class="select">
      <select>
        <option>$</option>
        <option>£</option>
        <option></option>
      </select>
    </span>
  </p>
  <p class="control is-expanded">
    <input class="input" type="text" placeholder="Amount of money">
  </p>
  <p class="control">
    <a class="button">
      Transfer
    </a>
  </p>
</div>

如果你想要一个全宽的下拉框,请将 control is-expandedselect is-fullwidth 配合使用。

<div class="field has-addons">
  <div class="control is-expanded">
    <div class="select is-fullwidth">
      <select name="country">
        <option value="Argentina">Argentina</option>
        <option value="Bolivia">Bolivia</option>
        <option value="Brazil">Brazil</option>
        <option value="Chile">Chile</option>
        <option value="Colombia">Colombia</option>
        <option value="Ecuador">Ecuador</option>
        <option value="Guyana">Guyana</option>
        <option value="Paraguay">Paraguay</option>
        <option value="Peru">Peru</option>
        <option value="Suriname">Suriname</option>
        <option value="Uruguay">Uruguay</option>
        <option value="Venezuela">Venezuela</option>
      </select>
    </div>
  </div>
  <div class="control">
    <button type="submit" class="button is-primary">Choose</button>
  </div>
</div>

U使用 has-addons-centeredhas-addons-right 修饰符来改变 对齐方式.

Transfer

<div class="field has-addons has-addons-centered">
  <p class="control">
    <span class="select">
      <select>
        <option>$</option>
        <option>£</option>
        <option></option>
      </select>
    </span>
  </p>
  <p class="control">
    <input class="input" type="text" placeholder="Amount of money">
  </p>
  <p class="control">
    <a class="button is-primary">
      Transfer
    </a>
  </p>
</div>

Transfer

<div class="field has-addons has-addons-right">
  <p class="control">
    <span class="select">
      <select>
        <option>$</option>
        <option>£</option>
        <option></option>
      </select>
    </span>
  </p>
  <p class="control">
    <input class="input" type="text" placeholder="Amount of money">
  </p>
  <p class="control">
    <a class="button is-primary">
      Transfer
    </a>
  </p>
</div>

表单组(Form group) #

如果想将控件 组合 在一起,请在 field 容器上使用 is-grouped修饰符。

<div class="field is-grouped">
  <p class="control">
    <a class="button is-primary">
      Submit
    </a>
  </p>
  <p class="control">
    <a class="button is-light">
      Cancel
    </a>
  </p>
</div>

使用is-grouped-centeredis-grouped-right 修饰符来改变 对齐方式.

<div class="field is-grouped is-grouped-centered">
  <p class="control">
    <a class="button is-primary">
      Submit
    </a>
  </p>
  <p class="control">
    <a class="button is-light">
      Cancel
    </a>
  </p>
</div>
<div class="field is-grouped is-grouped-right">
  <p class="control">
    <a class="button is-primary">
      Submit
    </a>
  </p>
  <p class="control">
    <a class="button is-light">
      Cancel
    </a>
  </p>
</div>

在需要 填充剩余空间 的元素上增加 is-expanded 修饰符。

<div class="field is-grouped">
  <p class="control is-expanded">
    <input class="input" type="text" placeholder="Find a repository">
  </p>
  <p class="control">
    <a class="button is-info">
      Search
    </a>
  </p>
</div>

添加 is-grouped-multiline 修饰符可以允许空间填充 多行,这是一个长列表的理想选择。

<div class="field is-grouped is-grouped-multiline">
  <p class="control">
    <a class="button">
      One
    </a>
  </p>
  <p class="control">
    <a class="button">
      Two
    </a>
  </p>
  <p class="control">
    <a class="button">
      Three
    </a>
  </p>
  <p class="control">
    <a class="button">
      Four
    </a>
  </p>
  <p class="control">
    <a class="button">
      Five
    </a>
  </p>
  <p class="control">
    <a class="button">
      Size
    </a>
  </p>
  <p class="control">
    <a class="button">
      Seven
    </a>
  </p>
  <p class="control">
    <a class="button">
      Eight
    </a>
  </p>
  <p class="control">
    <a class="button">
      Nine
    </a>
  </p>
  <p class="control">
    <a class="button">
      Ten
    </a>
  </p>
  <p class="control">
    <a class="button">
      Eleven
    </a>
  </p>
  <p class="control">
    <a class="button">
      Twelve
    </a>
  </p>
  <p class="control">
    <a class="button">
      Thirteen
    </a>
  </p>
</div>

按钮列表

如果您只需要一个 按钮 的列表,请尝试使用新的 buttons 类创建 按钮列表.


水平表单(Horizontal form) #

如果你想要一个 水平的 的表单控件,请在 field 容器上添加 is-horizontal 修饰符:

  • field-label for the side label
  • field-body for the input/select/textarea container

您可以在子元素上使用 is-groupedhas-addons

Do not enter the first zero

This field is required

<div class="field is-horizontal">
