在Agron原版主题中，顶部Banner仅有全局开关，不可针对各类页面做到分别启用。

为了提高文章可读性，提升用户阅读感受，应在文章阅览页禁用顶部Banner，为此，需要在页尾脚本与额外CSS中，增添代码以实现仅在首页启用顶部Banner。

因使Argon主题首页Banner标题打字动画支持HTML格式和在Agron主题中实现仅在首页启用顶部Banner会有部分冲突，为此将页尾脚本分为两个版本，即仅在Agron主题中实现仅在首页启用顶部Banner版本和包含使Argon主题首页Banner标题打字动画支持HTML格式版本。

页尾脚本（仅在Agron主题中实现仅在首页启用顶部Banner）：

<script>
(function () {
    function isSinglePostPage() {
        return document.querySelector('.page-information-card-container') !== null;
    }

    function updateBannerState() {
        var banner = document.getElementById('banner');
        if (!banner) return;

        // 先清理残留状态
        banner.style.removeProperty('display');
        document.body.classList.remove('article-no-banner');

        // 仅文章页隐藏 Banner
        if (isSinglePostPage()) {
            banner.style.setProperty('display', 'none', 'important');
            document.body.classList.add('article-no-banner');
        }

        // 通知页面重新计算布局
        setTimeout(function () {
            window.dispatchEvent(new Event('scroll'));
            window.dispatchEvent(new Event('resize'));
        }, 50);
    }

    function initBannerControl() {
        updateBannerState();
    }

    // 首次加载
    document.addEventListener('DOMContentLoaded', initBannerControl);

    // PJAX 完成
    document.addEventListener('pjax:complete', function () {
        setTimeout(initBannerControl, 50);
    });

    // 包装已有 pjaxLoaded，避免覆盖别的脚本
    var oldPjaxLoaded = window.pjaxLoaded;
    window.pjaxLoaded = function () {
        if (typeof oldPjaxLoaded === 'function') {
            oldPjaxLoaded();
        }
        initBannerControl();
    };

    // 兜底执行一次，清掉旧残留
    setTimeout(initBannerControl, 100);
})();
</script>

页尾脚本（包含使Argon主题首页Banner标题打字动画支持HTML格式）：

<script>

    function isSinglePostPage() {
        // 只认 single.php 中明确存在的标志
        return document.querySelector('.page-information-card-container') !== null;

    function updateBannerState() {
        var banner = document.getElementById('banner');
        if (!banner) return;

        // 每次先清理历史残留，避免首页被遗留的 display:none 影响
        banner.style.removeProperty('display');
        document.body.classList.remove('article-no-banner');

        // 只有文章页才隐藏 Banner
        if (isSinglePostPage()) {
            banner.style.setProperty('display', 'none', 'important');
            document.body.classList.add('article-no-banner');
