表单 - 纯净 - Pure.css 中文

默认表单

若要创建默认的内联表单，请向任何 <form> 元素添加 pure-form 类名。

<form class="pure-form">
    <fieldset>
        <legend>A compact inline form</legend>
        <input type="email" placeholder="Email" />
        <input type="password" placeholder="Password" />
        <label for="default-remember">
            <input type="checkbox" id="default-remember" /> Remember me
        </label>
        <button type="submit" class="pure-button pure-button-primary">Sign in</button>
    </fieldset>
</form>

堆叠表单

若要创建标签下方有输入元素的堆叠表单，请向 <form> 元素添加 pure-form-stacked 类名，同时添加 pure-form。

<form class="pure-form pure-form-stacked">
    <fieldset>
        <legend>A Stacked Form</legend>
        <label for="stacked-email">Email</label>
        <input type="email" id="stacked-email" placeholder="Email" />
        <span class="pure-form-message">This is a required field.</span>
        <label for="stacked-password">Password</label>
        <input type="password" id="stacked-password" placeholder="Password" />
        <label for="stacked-state">State</label>
        <select id="stacked-state">
            <option>AL</option>
            <option>CA</option>
            <option>IL</option>
        </select>
        <label for="stacked-remember" class="pure-checkbox">
            <input type="checkbox" id="stacked-remember" /> Remember me
        </label>
        <button type="submit" class="pure-button pure-button-primary">Sign in</button>
    </fieldset>
</form>

对齐表单

若要创建对齐表单，请向 <form> 元素添加 pure-form-aligned 类名，同时添加 pure-form。在对齐表单中，标签针对表单输入控件右对齐，但在较小的屏幕上会变回堆叠表单。

<form class="pure-form pure-form-aligned">
    <fieldset>
        <div class="pure-control-group">
            <label for="aligned-name">Username</label>
            <input type="text" id="aligned-name" placeholder="Username" />
            <span class="pure-form-message-inline">This is a required field.</span>
        </div>
        <div class="pure-control-group">
            <label for="aligned-password">Password</label>
            <input type="password" id="aligned-password" placeholder="Password" />
        </div>
        <div class="pure-control-group">
            <label for="aligned-email">Email Address</label>
            <input type="email" id="aligned-email" placeholder="Email Address" />
        </div>
        <div class="pure-control-group">
            <label for="aligned-foo">Supercalifragilistic Label</label>
            <input type="text" id="aligned-foo" placeholder="Enter something here..." />
        </div>
        <div class="pure-controls">
            <label for="aligned-cb" class="pure-checkbox">
                <input type="checkbox" id="aligned-cb" /> I&#x27;ve read the terms and conditions
            </label>
            <button type="submit" class="pure-button pure-button-primary">Submit</button>
        </div>
    </fieldset>
</form>

多列表单（使用 Pure 网格）

若要创建多列表单，请在Pure 网格中包含表单元素。创建自适应多列表单（如以下示例）要求网页上存在Pure 自适应网格。

<form class="pure-form pure-form-stacked">
    <fieldset>
        <legend>Legend</legend>
        <div class="pure-g">
            <div class="pure-u-1 pure-u-md-1-3">
                <label for="multi-first-name">First Name</label>
                <input type="text" id="multi-first-name" class="pure-u-23-24" />
            </div>
            <div class="pure-u-1 pure-u-md-1-3">
                <label for="multi-last-name">Last Name</label>
                <input type="text" id="multi-last-name" class="pure-u-23-24" />
            </div>
            <div class="pure-u-1 pure-u-md-1-3">
                <label for="multi-email">E-Mail</label>
                <input type="email" id="multi-email" class="pure-u-23-24" required="" />
            </div>
            <div class="pure-u-1 pure-u-md-1-3">
                <label for="multi-city">City</label>
                <input type="text" id="multi-city" class="pure-u-23-24" />
            </div>
            <div class="pure-u-1 pure-u-md-1-3">
                <label for="multi-state">State</label>
                <select id="multi-state" class="pure-input-1-2">
                    <option>AL</option>
                    <option>CA</option>
                    <option>IL</option>
                </select>
            </div>
        </div>
        <label for="multi-terms" class="pure-checkbox">
            <input type="checkbox" id="multi-terms" /> I&#x27;ve read the terms and conditions
        </label>
        <button type="submit" class="pure-button pure-button-primary">Submit</button>
    </fieldset>
</form>

分组输入

若要对文本输入元素进行分组，请使用类名为 pure-group 的 <fieldset> 元素将它们包装起来。分组输入非常适合注册表单，并且在移动设备上显得非常自然。

<form class="pure-form">
    <fieldset class="pure-group">
        <input type="text" class="pure-input-1-2" placeholder="Username" />
        <input type="text" class="pure-input-1-2" placeholder="Password" />
        <input type="email" class="pure-input-1-2" placeholder="Email" />
    </fieldset>
    <fieldset class="pure-group">
        <input type="text" class="pure-input-1-2" placeholder="A title" />
        <textarea class="pure-input-1-2" placeholder="Textareas work too"></textarea>
    </fieldset>
    <button type="submit" class="pure-button pure-input-1-2 pure-button-primary">Sign in</button>
</form>

输入调整大小

输入元素采用类似于Pure 网格的语法设置了流体宽度大小。您可将 pure-input-* 类应用到这些元素。

<form class="pure-form">
    <input type="text" class="pure-input-1" placeholder=".pure-input-1" />
    <br />
    <input type="text" class="pure-input-2-3" placeholder=".pure-input-2-3" />
    <br />
    <input type="text" class="pure-input-1-2" placeholder=".pure-input-1-2" />
    <br />
    <input type="text" class="pure-input-1-3" placeholder=".pure-input-1-3" />
    <br />
    <input type="text" class="pure-input-1-4" placeholder=".pure-input-1-4" />
    <br />
</form>

您还可以通过将输入元素包装到网格容器中，进一步控制输入大小。在以下示例中，<input> 元素具有 pure-input-1 类，但包装在类为特定网格的 <div> 中。

<form class="pure-form pure-g">
    <div class="pure-u-1-4">
        <input type="text" class="pure-input-1" placeholder=".pure-u-1-4" />
    </div>
    <div class="pure-u-3-4">
        <input type="text" class="pure-input-1" placeholder=".pure-u-3-4" />
    </div>
    <div class="pure-u-1-2">
        <input type="text" class="pure-input-1" placeholder=".pure-u-1-2" />
    </div>
    <div class="pure-u-1-2">
        <input type="text" class="pure-input-1" placeholder=".pure-u-1-2" />
    </div>
    <div class="pure-u-1-8">
        <input type="text" class="pure-input-1" placeholder=".pure-u-1-8" />
    </div>
    <div class="pure-u-1-8">
        <input type="text" class="pure-input-1" placeholder=".pure-u-1-8" />
    </div>
    <div class="pure-u-1-4">
        <input type="text" class="pure-input-1" placeholder=".pure-u-1-4" />
    </div>
    <div class="pure-u-1-2">
        <input type="text" class="pure-input-1" placeholder=".pure-u-1-2" />
    </div>
    <div class="pure-u-1-5">
        <input type="text" class="pure-input-1" placeholder=".pure-u-1-5" />
    </div>
    <div class="pure-u-2-5">
        <input type="text" class="pure-input-1" placeholder=".pure-u-2-5" />
    </div>
    <div class="pure-u-2-5">
        <input type="text" class="pure-input-1" placeholder=".pure-u-2-5" />
    </div>
    <div class="pure-u-1">
        <input type="text" class="pure-input-1" placeholder=".pure-u-1" />
    </div>
</form>

必填输入

若要将表单控件标记为必填，请添加 required 属性。

<form class="pure-form">
    <input type="email" placeholder="Requires an email" required="" />
</form>

禁用输入

若要禁用表单控件，请添加 disabled 属性。

<form class="pure-form">
    <input type="text" placeholder="Disabled input here..." disabled="" />
</form>

只读输入

如需使表单输入不可编辑，添加readonly属性。disabled和readonly之间的差异在于，不可编辑输入仍可聚焦。这允许用户与输入进行交互并选择其文本，而禁用控件不可交互。

<form class="pure-form">
    <input type="text" value="Readonly input here..." readonly="" />
</form>

圆角输入

如需显示圆角表单控件，添加pure-input-rounded类名。

<form class="pure-form">
    <input type="text" class="pure-input-rounded" />
    <button type="submit" class="pure-button">Search</button>
</form>

复选框和单选按钮

如需标准化和对齐复选框和单选按钮输入，添加pure-checkbox或pure-radio类名。

<form class="pure-form">
    <label for="checkbox-radio-option-one" class="pure-checkbox">
        <input type="checkbox" id="checkbox-radio-option-one" value="" /> Here&#x27;s option one.
    </label>
    <label for="checkbox-radio-option-two" class="pure-radio">
        <input type="radio" id="checkbox-radio-option-two" name="optionsRadios" value="option1" checked="" /> Here&#x27;s a radio button. You can choose this one..
    </label>
    <label for="checkbox-radio-option-three" class="pure-radio">
        <input type="radio" id="checkbox-radio-option-three" name="optionsRadios" value="option2" /> ..Or this one!
    </label>
</form>
