 We hear you, but we're not convinced that simply disabling our base styles is what you really want. You don't want to have to remove annoying margins every time you use a `p` element in a piece of your dashboard UI. And I doubt you really want your blog posts to use the user-agent styles either — you want them to look _awesome_, not awful.

 When a heading comes after a paragraph, we need a bit more space, like I already mentioned above. Now let's see what a more complex list would look like.
 
 - **I often do this thing where list items have headings.**
 
   For some reason I think this looks cool which is unfortunate because it's pretty annoying to get the styles right.
 
-  I often have two or three paragraphs in these list items too, so the hard part is getting the spacing between the paragraphs, list item heading, and separate list items to all make sense. Pretty tough honestly, you could make a strong argument that you just shouldn't write this way.

-Another thing I've done in the past is put a `code` tag inside of a link, like if I wanted to tell you about the [`tailwindcss/docs`](https://github.com/tailwindcss/docs) repository. I don't love that there is an underline below the tildes but it is absolutely not worth the madness it would require to avoid it.

 #### We haven't used an `h4` yet
 
-But now we have. Please don't use `h5` or `h6` in your content, Medium only supports two heading levels for a reason you animals. I honestly considered using a `before` pseudo-element to scream at you if you use an `h5` or `h6`.

 We don't style them at all out of the box because `h4` elements are already so small that they are the same size as the body copy. What are we supposed to do with an `h5`, make it _smaller_ than the body copy? No thanks.
