You can see a full demo of this in an actual GitHub readme in my eRCaGuy_hello_world repo here. It relies on the deprecated HTML align attribute, but still works fine. This works in any GitHub *.md markdown file, such as a GitHub readme.md file. Centering and aligning images in GitHub readmes using the deprecated HTML align attribute: Option 2 only works in places where you have full control over CSS styles, such as in a custom GitHub Pages website you make maybe?ġ.

So, that means to center or align images in GitHub readmes, your only solution is to use the deprecated HTML align attribute (that happens to still function), as this answer shows. The HTML is sanitized, aggressively removing things that could harm you and your kin-such as script tags, inline-styles, and class or id attributes.

'A Markdown-formatted document should be publishable as-is, as plain text, without looking like it’s been marked up with tags or formatting instructions. In fact, it would be borderline against the Markdown philosophy to allow such formatting, as stated in the ' Philosophy' section. The Markdown syntax doesn't provide one with the ability to control the position of an image. The wiki, for instance, won't allow such CSS positional trickery. Note 2: Keep in mind that even within the GitHub website, the way Markdown is rendered is not uniform. īeware that there's no guarantee the image will be centered if your repository is forked in a different hosting environment ( CodePlex, Bitbucket, etc.) or if the document isn't read through a browser ( Sublime Text Markdown preview, MarkdownPad, Visual Studio Web Essentials Markdown preview.
