在HTML中,我有以下内容：

<uib-accordion-heading>
    <div id="fart1" ng-if="!contactsAccordionIsOpen" class="noSelect" style="outline: none;">Contacts<span class="glyphicon glyphicon-plus-sign pull-right"></span></div>
    <div id="fart2" ng-if="contactsAccordionIsOpen" class="noSelect" style="outline: none;">Contacts<span class="glyphicon glyphicon-minus-sign pull-right"></span></div>
</uib-accordion-heading>

整个手风琴标题周围没有出现蓝色轮廓,但形状适合文本.我尝试过内联样式,按ID和类选择,但即使有！重要但它不会改变.

在CSS我有：

#fart1:focus {
    border: none !important;
    outline: none !important;
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

#fart2:focus {
    border: none !important;
    outline: none !important;
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

.noSelect {
    border: none !important;
    outline: none !important;
    outline-width: 0 !important;
    -webkit-touch-callout: none !important;
    -webkit-user-select: none !important;
    -khtml-user-select: none !important;
    -moz-user-select: none !important;
    -ms-user-select: none !important;
    user-select: none !important;
}

我也尝试过交换大纲：没有大纲：0但它没有改变任何东西.

编辑 – 附上一张图片来说明我所说的内容.

:focus {outline:0 !important;}

此代码全部重点边框删除.
