Twitter Bootstrap输入不附加容器的全宽

Question

我有一个网站建立Twitter Bootstrap.

在构建2列表单时,我尝试使用input-prepend该类在表单输入的左侧添加电子邮件图标.我希望输入字段和前置图标始终是容器的100%.

这是我的代码:

                      <div class='row-fluid'>
                        <div class='span6'>
                          <div class='control-group' id='contactEmailControlGroup'>
                            <label for='contactEmail'>Email Address</label>
                              <div class='input-prepend'> <span class='add-on'><i class='icon-envelope'></i></span>
                                <input type='email' name='contactEmail' id='contactEmail' class='span11' placeholder='Your email address...' tabindex='3' required/>
                                <span class='help-inline formAlert' id='contactEmailError'> <i class='icon-edit formAlertIcon'></i> Please enter your email address </span> <span class='help-inline formAlert' id='contactEmailInvalidError'> <i class='icon-exclamation-sign formAlertIcon'></i> Invalid email address </span>
                            </div>
                          </div>
                        </div>
                        <div class='span6'>
                          <div class='control-group'>
                            <label for='contactPhone'>Phone Number</label>
                            <input type='tel' name='contactPhone' id='contactPhone' class='span12' placeholder='Your phone number...' tabindex='4' required/>
                            <span class='help-inline formAlert' id='contactPhoneError'> <i class='icon-edit formAlertIcon'></i> Please enter your phone number </span> <span class='help-inline formAlert' id='contactPhoneInvalidError'> <i class='icon-exclamation-sign formAlertIcon'></i> Invalid phone number </span> </div>
                        </div>
                      </div>

使用此代码时,表单如下所示:

但是,当我调整浏览器大小以模拟较小的屏幕时,add-on前置字段的宽度大小不正确,如下所示:

题

• 是否应该对此表单进行编码以使输入字段和图标为100%并与其他字段匹配？
• 或者我需要在Bootstrap中更改哪些CSS来更改它？

Answer 1

Bootstrap 3还没有出来,所以这是我简单而有效的解决方案,适用于追加和前置情况.在Bootstrap CSS/LESS文件之后包含这个:

.input-append.input-block-level,
.input-prepend.input-block-level {
  display: table;
}

.input-append.input-block-level .add-on,
.input-prepend.input-block-level .add-on {
  display: table-cell;
  width: 1%; /* remove this if you want default bootstrap button width */
}

.input-append.input-block-level > input,
.input-prepend.input-block-level > input {
  box-sizing: border-box; /* use bootstrap mixin or include vendor variants */
  display: table; /* table-cell is not working well in Chrome for small widths */
  min-height: inherit;
  width: 100%;
}

.input-append.input-block-level > input {
  border-right: 0;
}

.input-prepend.input-block-level > input {
  border-left: 0;
}

在HTML中使用它,请记住,在这种情况下,您必须使用a不是button按钮的标签:

<div class="input-append input-block-level">
  <input type="text" />
  <a class="btn add-on">click</a>
</div>
