Slick.js 删除图像周围的蓝色突出显示

我正在使用 Slick.js 在模态中构建轮播。一切都很完美，直到我点击图像。出现蓝色边框，不幸的是我不知道如何让它停止这样做。我尝试过“outline:none”和“border:none”，但都没有成功。这是我的代码

HTML:

<div id="openModal" class="modalDialog">
    <div id ="background">
        <a href="#close" title="Close" class="close">X</a>
            <div id="logo">
                <img src="/media/{{ gallery.logo }}" alt="Smiley face" height="100" width="150">
            </div>
            <div class="multiple-items">
                        <div><img src="/media/{{ gallery.image1 }}" height="200" width="300"></div>
                        <div><img src="/media/{{ gallery.image2 }}" height="200" width="300"></div>
                        <div><img src="/media/{{ gallery.image3 }}" height="200" width="300"></div>
                        <div><img src="/media/{{ gallery.image4 }}" height="200" width="300"></div>
                        <div><img src="/media/{{ gallery.image5 }}" height="200" width="300"></div>
                        <div><img src="/media/{{ gallery.image6 }}" height="200" width="300"></div>
            </div>
        </div>
</div>

CSS:

/* Slider */
 .slick-slider {
    margin: 110px 35px 0 0;
    position: relative;
    display: block;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
    -webkit-user-select: none;
    -moz-user-select: none;

    touch-action: pan-y;
    -webkit-tap-highlight-color: transparent;
}
.slick-list {
    position: relative;
    display: block;
    overflow: hidden;
    margin: 0;
    padding: 0;
}
.slick-list:focus {
    outline: none;
}
.slick-list.dragging {
    cursor: pointer;
    cursor: hand;
}
.slick-slider .slick-track, .slick-slider .slick-list {
    -webkit-transform: translate3d(0, 0, 0);
    -moz-transform: translate3d(0, 0, 0);
    -ms-transform: translate3d(0, 0, 0);
    -o-transform: translate3d(0, 0, 0);
    transform: translate3d(0, 0, 0);
}
.slick-track {
    position: relative;
    top: 0;
    left: 0;
    display: block;
}
.slick-track:before, .slick-track:after {
    display: table;
    content:'';
}
.slick-track:after {
    clear: both;
}
.slick-loading .slick-track {
    visibility: hidden;
}
.slick-slide {
    display: none;
    float: left;
    height: 100%;
    min-height: 1px;
}
[dir='rtl'] .slick-slide {
    float: right;
}
.slick-slide img {
    display: block;
}
.slick-slide.slick-loading img {
    display: none;
}
.slick-slide.dragging img {
    pointer-events: none;
}
.slick-initialized .slick-slide {
    display: block;
    background-color: green;
    border: none;
}
.slick-loading .slick-slide {
    visibility: hidden;
}
.slick-vertical .slick-slide {
    display: block;
    height: auto;
    border: 1px solid transparent;
}
.slick-arrow.slick-hidden {
    display: none;
}
.slider {
    width: 80%;
    margin: 40px 0 0 100px;
}
.lower {
    margin-top: 100px;
}
.slick-slide {
    color: white;
    padding: 30px;
    font-size: 30px;
    font-family:"Arial";
    margin: 0 -50px 0 0;
}
.slick-prev:before, .slick-next:before {
    color: black;
}
.slick-slide:nth-child(1), .slick-slide:nth-child(3), .slick-slide:nth-child(5), .slick-slide:nth-child(7), .slick-slide:nth-child(9), .slick-slide:nth-child(11) {
}
.slick-slide slick-current slick-active {
    display: none;
    color: red;
}
.slick-slide slick-active {
    display: none;
}
.slick-active img {
    outline: 0 !important;
    border:0 none !important;
}
.multiple-items img {
    outline: 0 !important;
    border:0 none !important;
}

JQuery:

$(document).ready(function(){
    $('.multiple-items').slick({
      infinite: false,
      arrows: false,
      slidesToShow: 3,
      slidesToScroll: 1,

});
  });

EDIT:

这是一个链接JSFiddle https://jsfiddle.net/codemesoftly/x09xryyv/。当您打开模式时，您将看到里面的图像。单击图像后，图像周围会出现一个蓝色框。这就是我想要消除的。

你需要使用outline: none;

穿上.slick-slide

.slick-slide {
    outline: none
}
