How to Automatically Generate an Article Summary in Webflow

In this tutorial, Sandro, cofounder of Gemeos Webflow agency, shows you how to automatically generate a summary of your Webflow articles from the first paragraphs of the content.

Example

1. Add the elements in Webflow

Create a Div container with display: none by default containing a Text Block with the ID article-summary. Place it at the top of your article, before the content. Add the article-content class to your Rich Text content area.

2. Add the script in Footer code

(function() {
  var content = document.querySelector('.article-content');
  var target = document.getElementById('article-summary');
  if (!content || !target) return;

  var paragraphs = content.querySelectorAll('p');
  var sentences = [];

  paragraphs.forEach(function(p) {
    if (sentences.length >= 3) return;
    var text = p.textContent.trim();
    if (text.length < 50) return;
    var parts = text.match(/[^.!?]+[.!?]+/g) || [text];
    parts.forEach(function(s) {
      if (sentences.length < 3 && s.trim().length > 40) {
        sentences.push(s.trim());
      }
    });
  });

  if (sentences.length === 0) return;
  target.textContent = sentences.join(' ');
  target.parentElement.style.display = 'block';
})();

Conclusion

An automatic summary improves readability and helps busy readers decide whether the article is worth their time. Use cases:

• Long blog articles with multiple sections
• Technical documentation pages
• Newsletters with article excerpts
