CKEditor前端样式和编辑器的样式不一致的问题

前言

这样子在使用CKEditor里面的快引用的功能,但是发现编辑器里面的快引用和我们前端页面显示的样式不一致,下图是我们编辑器里的样式

然后下图是我们页面中的样式,发现CKEditor里的快引用是无法正常显示的

后面通过查阅官方文档:传送门

文档中,给出了相应的两种解决方案

  • 在前端也安装一个CKEditor编辑器
  • 引入官方给定的CSS

首先对于第一种方案,官方是持否定态度的:

默认情况下,内容样式由编辑器JavaScript加载,这使得它们只在用户编辑其内容时出现,而这通常在应用程序的后端发生。如果您想在前端使用相同的样式,您可能会发现自己处于这样一种情况,需要您为此加载CKEditor,这(就性能而言)不是最好的主意。为了避免在你的前端不必要的依赖,使用一个完整的CKEditor 5内容样式列表样式表所有编辑器功能。有两种方法可以获得它

因此我们就引入给定的CSS样式

/* ckeditor5-code-block/theme/codeblock.css */
.ck-content pre code {
    background: unset;
    padding: 0;
    border-radius: 0;
}
@media print {
    /* ckeditor5-page-break/theme/pagebreak.css */
    .ck-content .page-break {
        padding: 0;
    }
    /* ckeditor5-page-break/theme/pagebreak.css */
    .ck-content .page-break::after {
        display: none;
    }
}

但是官方的CSS样式,对于h1,h2等标签没有很好的处理,因此我们再次加入自己的自定义css进去

.ck-content p {
  margin: 12px 0 !important;
}

.ck-content a {
  text-decoration: underline !important;
  color: #00e !important;
}

.ck-content ul li {
  list-style: disc;
}

.ck-content ol li {
  list-style: decimal;
}

.ck-content ul,
.ck-content ol {
  padding-left: 40px !important;
  padding-right: 40px !important;
}

.ck-content li {
  display: list-item !important;
}

.ck-content h1 {
  font-weight: bold !important;
  font-size: 32px !important;
  margin: 21px 0 !important;
}

.ck-content h2 {
  font-weight: bold !important;
  font-size: 24px !important;
  margin: 19px 0 !important;
}

.ck-content h3 {
  font-weight: bold !important;
  font-size: 19px !important;
  margin: 18px 0 !important;
}

.ck-content h4 {
  font-weight: bold !important;
  font-size: 16px !important;
  margin: 21px 0 !important;
}

.ck-content h5 {
  font-weight: bold !important;
  font-size: 13px !important;
  margin: 22px 0 !important;
}

.ck-content h6 {
  font-weight: bold !important;
  font-size: 11px !important;
  margin: 24px 0 !important;
}

添加进去后,我们就能够看到快引用已经能够正常的显示了
