Using long words that can't break
When you use unusually long words (looking at you, Germans) in a Webflow project, this can cause the layout to break, especially on lower resolution devices.
Example
The following is the longest word in english language, consisting of 45 characters. It will not break properly and will cause horizontal scroll on resolutions below 504px. (for this specific font)
