Hi Alex,  
I think @Moin has the right idea–I’m seeing some styling applied to the code blocks that looks like it’s probably coming from **Custom CSS/HTML** in the theme.

 ![This image shows a computer screen displaying a code editor with a Python script that includes various imports and function definitions. (Captioned by AI)](https://global.discourse-cdn.com/meta/original/4X/5/5/5/555d09462f6f6609457d1c749582ff2d9bebc843.png)

I think this line (`font-family: Consolas;`) could be safely removed since it’s overriding these existing styles which use the same font but also specify fallback options:

```css
code, pre {
    font-family: var(--d-font-family--monospace);
}

:root {
    --d-font-family--monospace: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace;
}

```

Maybe your computer isn’t able to display Consolas and is just falling back to the default (non-monospace) font. You can check here to see if that CSS is present:
