Joe文章列表添加渐变颜色效果
https://www.iarc.top/452.html
2024-07-07T00:41:00+08:00
一个大气的文章列表CSS渐变动画，也可以使用图片作为渐变背景，，效果如下(鼠标移动到元素上后颜色会更加突出)：日间模式夜间模式接下来需要编辑的文件以及相对Joe主题的文件路径：joe.index.js /Joe/assets/jsjoe.index.css /Joe/assets/cssjoe.mode.css/Joe/assets/css开始（共三部分）{tabs}{tabs-pane label="添加HTML代码"}打开joe.index.js文件找到如图所示位置可以直接搜joe_list__item wow default定位到，其实一打开就是了。在第一个a标签元素后面加入如下代码<div class="article-banner-wrap"></div>
<div class="article-banner"></div>{/tabs-pane}{tabs-pane label="添加CSS代码"}直接将下面的css代码复制粘贴到joe.index.css文件的最后面就行了/*首页列表渐变*/
.article-banner-wrap {
position: absolute;
height: 100%;
width: 50%;
right: 0;
top: 0;
}
.article-banner {
visibility: hidden;
opacity: .2;
position: absolute;
height: 100%;
width: 50%;
right: 0;
top: 0;
z-index: 0;
background-repeat: no-repeat;
background-size: cover;
-webkit-background-size: cover;
-o-background-size: cover;
background-position: center center;
transition: opacity 0.2s;
-webkit-mask-image: -webkit-linear-gradient(right, rgba(0, 0, 0, 1) 0%, rgba(0, 0, 0, 0) 100%);
border-radius: 8px;
background:linear-gradient(to left,#2BC0E4,#EAECC6);
visibility: visible;
animation: banner-show 1s;
}
.joe_list__item.default:hover .article-banner{opacity: 1;}其中的background可以改成图片地址，这样效果就是图片了，但图片会拖累网站加载速度，可自行决定是否要换成图片。{/tabs-pane}{tabs-pane label="适配夜间模式"}打开joe.mode.css文件，将以下CSS代码加入文件底部即可。/*首页列表图片渐变夜间模式*/
html[data-night='night'] .article-banner{
background: linear-gradient(to left,#1F1C2C,#928DAB);
opacity:0.1
}我这里不是最底部是因为我后来又加其他东西了，其实也不是一定要最底部，只是方便小白操作和自己描述了。{/tabs-pane}{/tabs}

给博客评论框添加一个简单的滑动背景图
https://www.iarc.top/417.html
2024-03-18T18:06:00+08:00
纯css实现，代码各个主题都是通用的，这里以Joe主题为例效果：css代码：.joe_comment__respond-form .body{padding:15px;background:url(https://www.iarc.top/usr/uploads/2024/03/1257364055.png);background-position:right;background-repeat:no-repeat;resize:none;}.joe_comment__respond-form .body:hover{background-position-x:4000px;transition:ease-in-out 2s;}.joe_comment__respond-form .body 就是评论框主题，可以直接在前端按F12查看自己主题的是哪个组图片：最好自己保存下来，以防失效。

为自己博客or网页加上鼠标流光背景JS特效
https://www.iarc.top/264.html
2023-07-02T16:06:00+08:00
鼠标流光背景特效（乱起的名别太在意 :@(献花) ），canvas画布配合JS即可实现，这个版本是我从一个人单页里面抄下来的，顺便优化了一下后将其加入到了本站夜间模式{card-default label="快速实现" width=""}<canvas id="sbcanvas" class="sbcanvas"></canvas>
<script src="https://www.iarc.top/CDN/js/sbxg.js"></script>
<style>
.sbcanvas{
display: block;
position: fixed;
top: 0;
z-index: -9;
}
</style>{/card-default}将特效设为博客夜间模式1.先在body写入<canvas id="sbcanvas" class="sbcanvas"></canvas>
<script src="https://www.iarc.top/CDN/js/sbxg.js"></script>2.更改css属性display为none（日间模式不显示该元素）.sbcanvas{
display: none;
position: fixed;
top: 0;
z-index: -9;
}
</style>3.在joe.mode.css文件夹最下面加入以下代码html[data-night='night'] .sbcanvas{display:block;}完成以上操作即可大功告成，快去开启夜间模式试一下吧
