分享论坛能用上的代码

小小白哦

一、楷体

原文：https://discuss.flarum.org.cn/d/4390

1. 打开 Flarum 「管理后台」，在「外观」的「自定义页眉」（Custom Header）加入如下代码：

<link href="https://cdn.staticfile.org/lxgw-wenkai-screen-webfont/1.7.0/lxgwwenkaiscreen.css" rel="stylesheet">

上述 1.7.0 是该开源库中本字体的版本号，最新版本号请在 Staticfile.org 查阅

2. 在「自定义样式」（Custom Styles）加入如下代码：

body {
  font-family: LXGW WenKai Screen, serif;
}
h1, h2, h3, h4, .TagsLabel, .Button, .DiscussionListItem-count, .item-discussion-views {
  font-family: LXGW WenKai Screen, sans-serif;
}

至此，自定义字体设置教程完毕，你可以刷新网页看看效果。

二、电脑端顶部导航栏高斯模糊

原文：https://discuss.flarum.org.cn/d/4120

@media (min-width:768px) {
    #header {
        & when (@config-dark-mode = false) {
            background:rgba(255,255,255,0.6) !important;
            -webkit-backdrop-filter:blur(8px);

    .sideNavContainer {
        display: flex;
        flex-direction: row-reverse;
    }

四、欢迎横幅无法被关闭

.Hero-close {
 display:none;
}

五、搜索优化并高亮

原文：https://discuss.flarum.org.cn/d/3390

/* 搜索高亮 */
mark {
    background: #FFE300 !important;
    padding: 2px 7px;
    border-radius: 7px;
    box-shadow: 0px 1px 5px rgba(0,0,0,0.2) !important;

    background-color: #ffcacaff;
    border-radius: 3em;
}
::-webkit-scrollbar {

    color: #ffffff;
    font-weight: bold;
    border-radius: 5px;
    text-align: center;
    font-size: 16px;
    display: block;
    margin: 5px 0;
}

十四、点赞和回复图标

原文：https://discuss.flarum.org.cn/d/2640

.item-like .Button--link .Button-label,.item-dislike .Button--link .Button-label,.item-reply .Button--link .Button-label {

	margin-right: 4px;
	vertical-align: -2px;
}

十五、实时显示 FPS & 网络延迟（HTML）

FPS: <span id="fps">0</span>
    <script>(function() {
    var fpsElement = document.getElementById('fps');
    var lastTime = 0;
    var frames = 0;

function calculateFps() {
    var now = performance.now();
    frames++;

    if (now - lastTime >= 1000) { // 每秒钟计算一次FPS
        fpsElement.textContent = frames;
        lastTime = now; // 更新时间戳
        frames = 0; // 重置计数器
    }

    requestAnimationFrame(calculateFps); // 继续动画循环
}

requestAnimationFrame(calculateFps); // 开始动画循环
})();</script>|
延迟：<span id="latency">正在计算...</span> ms
    <script>(function() {
    var latencyElement = document.getElementById('latency');

function measureLatency() {
    var startTime = performance.now();
    fetch('/path-to-server-endpoint')
        .then(response => response.text())
        .then(() => {
            var latency = Math.round(performance.now() - startTime);
            latencyElement.textContent = latency;
        })
        .catch(error => {
            console.error('Error measuring latency:', error);
            latencyElement.textContent = 'Error';
        });
}

// 每5秒测量一次网络延迟
setInterval(measureLatency, 5000);
})();</script>
