4. 参考1，进入博客设置旁边的 选项，点进入之后关闭 日历，分类 可按各自需求关闭。

5. 增加鼠标动效

先需要 申请JS权限，申请入口见标题2图，博客皮肤 的下方，审核需要稍等一会。

然后打开 页脚html代码

粘贴如下代码：

<!-- 鼠标动效 -->
<script src="https://files.cnblogs.com/files/wkfvawl/mouse-click.js"></script>
<canvas width="1777" height="841" style="position: fixed; left: 0px; top: 0px; z-index: 2147483647; pointer-events: none;"></canvas>

6. 公告增加头像框

需要先去相册里上传个人的头像，拿到上传后的头像地址

然后进入 博客侧边栏公告

粘贴如下代码，头像地址请换成自己的

<div class="headImage">
    <img src="https://images.cnblogs.com/cnblogs_com/blogs/xxxx.jpg" alt="头像">
</div>
<style>
#blog-news {
    display: flex;
    background: #fff;
}
#blog-news .headImage {
    width: 40%;
    display: flex;
    align-items: center;
    justify-content: center;
    border: solid 1px #dedede;
    border-right: none;
    border-radius: 0 0 0 10px;
}
#blog-news .headImage > img{
    width: 80%;
    border-radius: 50%;
}
#profile_block {
    flex: 1;
    border-radius: 0 0 10px 0;
}
#profile_block:hover {
    border-color: #dedede
}
/* 搜索按钮 */
