Tab content formatting
Tab content formatting is set by the theme
All tab content is rendered exactly as it is provided. Tabs Studio does not modify the content in any way, and it does not automatically apply or remove colors, font families, font sizes, borders, margins, padding, table widths, bullet points, or any other styling.
All tab content styling is inherited from the theme, unless it’s overridden by formatting applied with the rich text editor.
Copying and pasting content can apply unwanted formatting
Content copied from a webpage, document, PDF, or other source will try to retain its source formating, including font sizes, font families, colors, and spacing, when it's pasted into Shopify's rich text editor.
