Custom CSS

Adding custom styles to the newsletter.

What is custom CSS in Substack?

Custom CSS in Substack refers to the ability to modify the design and layout of a Substack newsletter using Cascading Style Sheets (CSS). CSS is a style sheet language used for describing the look and formatting of a document written in HTML. Substack allows users to add custom CSS to their newsletters, enabling them to change the appearance of their text, layout, and design elements to better fit their brand or personal style.

This feature is particularly useful for users who have a specific vision for their newsletter's aesthetics or want to maintain consistent branding across all their platforms. However, it's important to note that using custom CSS in Substack requires a basic understanding of CSS coding. Users without this knowledge may find it challenging to implement their desired changes.

How to add custom CSS in Substack?

Substack does not currently support the direct addition of custom CSS. The platform is designed to be simple and user-friendly, focusing on content creation rather than website design. Therefore, it does not provide an option for users to add or modify CSS to customize the look of their newsletters or pages.

However, you can customize the look of your Substack page to some extent using the options provided in the settings. You can change the color scheme, add a logo, and modify the header image. If you need more advanced customization, you might need to consider using a different platform that supports custom CSS.

Can you use custom CSS in Substack?

Yes, you can use custom CSS in Substack. Substack allows users to customize their newsletters using CSS to make them more visually appealing and unique. This feature is particularly useful for users who have a good understanding of CSS and want to create a more personalized look for their newsletters.

However, it's important to note that Substack's CSS customization options may not be as extensive as those offered by other platforms. The platform is designed to be simple and user-friendly, so while it does offer some customization options, it may not be the best choice for users who want complete control over every aspect of their newsletter's design.

Why is my custom CSS not working in Substack?

There could be several reasons why your custom CSS is not working in Substack. One of the main reasons could be that Substack does not support custom CSS. Substack is designed to be a simple platform for writers, and as such, it doesn't allow for much customization beyond what's offered in their built-in themes. This is to ensure that all newsletters have a consistent look and feel, and to keep the platform user-friendly for those without coding knowledge.

Another possible reason could be an error in your CSS code. Even if Substack did support custom CSS, any mistakes in your code, such as missing brackets, incorrect syntax, or misspelled properties could prevent it from working correctly. It's always a good idea to double-check your code for errors. However, as of now, Substack does not support custom CSS, so any changes you're trying to make with it will not be reflected on the platform.
