If you want to add space between elements easily without having to worry about paddings and margins, simply add spacer.
You can do this by adding a div, and giving it an appropriate class, such as "Spacer 4". Or copy existing one.
Note: These example spacers are coloured grey for you to see their size, but usually they are transparent.
This design system uses independent column system for organising different content.12-columns-row is an 12 unit wide row, which you can insert columns inside
.Columns are added by adding an div and giving it a class of "Column".
Then you can add appropriate size for the column, which happens by giving columns combo classes.
The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.
A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!
Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
Also Webflow grids are used.
