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.

Webflow is a no-code website builder that generates clean HTML, CSS, and JavaScript. It lets you build professional websites without writing a single line of code.

The combination of the visual Designer and the built-in CMS makes it the ideal tool for agencies and marketing teams that want high-performing, maintainable websites.

Since 2020, Gemeos has supported startups and scale-ups with their Webflow strategy, with more than 80 projects delivered in France and internationally.

ParameterValueDescription
Number of sentences3Can be changed in the script
Minimum sentence length40 charactersFilters out sentences that are too short
Source'.article-content'Class to add to your article area
Targetid='article-summary'Text Block that receives the summary

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.

(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
