Jekyll Static Website Generator: Create customizable HTML widgets without Ruby plug-in

Jekyll, this lightweight static website generator, is popular for its powerful features and ease of use. This article will explain how to create customizable HTML widgets using Jekyll and Liquid template languages, without any Ruby plug-ins, and even non-technical people can easily get started.

Set custom variables

This article will introduce two methods to set custom variables: inline method and pre-content method.

1. Inline variable

Inline method is the best option if a widget may be included in the same page multiple times (such as a blog post). The following is an example of the PayPal button:

First, create a new file named _includes in the paypal-widget.html folder and add the following code:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
  <input type="hidden" name="cmd" value="_s-xclick">
  <input type="hidden" name="hosted_button_id" value="{{ include.id }}">
  <input type="submit" class="buy-button" name="submit" value="{{ include.button }}">
  <img src="/static/imghw/default1.png"  data-src="https://img.php.cn/upload/article/000/000/000/173985127475091.gif"  class="lazy"  alt="" border="0"    style="max-width:90%"  style="max-width:90%" style="display: none !important;">
</form>

include.id and include.button are two custom variables. When including this widget in the Markdown article, just write this:

{% include paypal-widget.html id="YOUR_PAYPAL_BUTTON_ID" button="立即購(gòu)買 | " %}

This creates a button marked "Buy Now | $30". You can include the same file multiple times, each time using different include.id and include.button values.

2. Pre-content variable

For longer text strings and widgets that only contain once per article, the pre-content method can be used. The following is an example of the news subscription box:

Same, create a new file in the _includes folder, for example signup-widget.html and add the following code:

<div class="signup-cta">
  <h2>{{ page.cta.title }}</h2>
  <p>{{ page.cta.body }}</p>
  <form method="POST">
    <input type="text" id="name" placeholder="姓名">
    <input type="email" placeholder="郵箱地址">
    <input type="submit" value="{{ page.cta.button }}">
  </form>
</div>

In the prefix of a Markdown article or page, use YAML to define variables:

---
cta:
  title: "訂閱我們的新聞"
  body: "喜歡這篇文章?訂閱我們的新聞,每天接收更多精彩內(nèi)容!"
  button: "立即訂閱!"
---

Then, include the widget in the article:

{% include signup-widget.html %}

What is 'render-blocking CSS'? What is 'render-blocking CSS'? Jun 24, 2025 am 12:42 AM

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
