Question

我正在尝试将清除按钮附加到输入搜索中，但是我得到的结果确实很奇怪，尤其是：

我怀疑此问题与我正在使用“ Black Dashboard PRO”的主题有关

<form>
    <div class="input-group">
        <input id="customer-search" type="text" class="key form-control" placeholder="Search">
        <span class="input-group-addon">
        <div>
            <button class="clear btn btn-default" type="button" title="Clear">
                <span class="tim-icons icon-simple-remove"></span>
            </button>
        </div>
        </span>
    </div>
</form>

这是主题使用的按钮的css：

`.btn:not(:disabled):not(.disabled) {
    cursor: pointer;
}
button, html [type="button"], [type="reset"], [type="submit"] {
    -webkit-appearance: button;
}
.btn {
    cursor: pointer;
}
.btn, .navbar .navbar-nav > a.btn {
    border-width: 2px;
    border: none;
    position: relative;
    overflow: hidden;
    margin: 4px 1px;
    border-radius: 0.4285rem;
    cursor: pointer;
    background: #344675;
    background-image: linear-gradient(to bottom left, #344675, #263148, #344675);
    background-size: 210% 210%;
    background-position: top right;
    background-color: #344675;
    transition: all 0.15s ease;
    box-shadow: none;
    color: #ffffff;
}
.btn-default {
    color: #ffffff;
    background-color: #344675;
    border-color: #344675;
    box-shadow: 0 4px 6px rgba(50, 50, 93, 0.11), 0 1px 3px rgba(0, 0, 0, 0.08);
}
.btn {
    display: inline-block;
    font-weight: 600;
    text-align: center;
    white-space: nowrap;
    vertical-align: middle;
    -webkit-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
    border: 1px solid transparent;
    padding: 11px 40px;
    font-size: 0.875rem;
    line-height: 1.35em;
    border-radius: 0.25rem;
    transition: color 0.15s ease-in-out, background-color 0.15s ease-in-out, border-color 0.15s ease-in-out, box-shadow 0.15s ease-in-out;
}`

删除'.btn，.navbar .navbar-nav> a.btn'的边距

{{1}}

Answer 2

我想您只需要删除该按钮上的边距即可查看演示

.btn:not(:disabled):not(.disabled) {
    cursor: pointer;
}
button, html [type="button"], [type="reset"], [type="submit"] {
    -webkit-appearance: button;
}
.btn {
    cursor: pointer;
}
.btn, .navbar .navbar-nav > a.btn {
    border-width: 2px;
    border: none;
    position: relative;
    overflow: hidden;
    margin: 4px 1px;
    border-radius: 0.4285rem;
    cursor: pointer;
    background: #344675;
    background-image: linear-gradient(to bottom left, #344675, #263148, #344675);
    background-size: 210% 210%;
    background-position: top right;
    background-color: #344675;
    transition: all 0.15s ease;
    box-shadow: none;
    color: #ffffff;
}
.btn-default {
    color: #ffffff;
    background-color: #344675;
    border-color: #344675;
    box-shadow: 0 4px 6px rgba(50, 50, 93, 0.11), 0 1px 3px rgba(0, 0, 0, 0.08);
}
.btn {
    display: inline-block;
    font-weight: 600;
    text-align: center;
    white-space: nowrap;
    vertical-align: middle;
    -webkit-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
    border: 1px solid transparent;
    padding: 11px 40px;
    font-size: 0.875rem;
    line-height: 1.35em;
    border-radius: 0.25rem;
    transition: color 0.15s ease-in-out, background-color 0.15s ease-in-out, border-color 0.15s ease-in-out, box-shadow 0.15s ease-in-out;

Answer 3

更改HTML和在跨度input-group-append

上添加类

<div class="input-group">
        <input id="customer-search" type="text" class="key form-control" placeholder="Search">
        <span class="input-group-append">
           <button class="clear btn btn-default" type="button" title="Clear">
              <span class="tim-icons icon-simple-remove">X</span>
           </button>
        </span>
    </div>
