我有这个摘录功能

     <?php
   function pietergoosen_get_the_content_limit_custom_allowedtags() {
    // Add custom tags to this string
        return \'<head>,<title>,<base>,<link>,<meta>,<style>,<script>,<noscript>,<body>,<section>,<nav>,
        <article>,<aside>,<h1>,<h2>,<h3>,<h4>,<h5>,<h6>,<header>,<footer>,<address>,<main>,<p>,<hr>,

    }

    function pietergoosen_custom_wp_trim_excerpt($text) {

一切都按预期进行，除了Read more about this article... 出现在摘录后的单独段落中，而不是出现在默认摘录的最后一个单词旁边。在google中，我可以看到wordpress添加了<p> 标记周围的Read more about this article 我怎样才能解决这个问题。

Bold letters inside excerpt

我目前正在尝试将摘录中的一些单词用“h1”标记加粗，但它似乎不起作用。当我在网上查看时，我所听到的只是建议使用插件。有没有一种方法可以在没有插件的情况下实现这一点。我的CSS如下所示。.side-bar h1 { font-weight: bold!important; }
