Code block background not being rendered in markdown

[DVAlexHiggs]

Describe the bug

When serving and viewing dbt docs, code blocks in markdown appear invisible. Upon highlighting them, the text is shown.

I believe this is due to the fact that there is white text on a white background, whereas it's usually white text on a blue background. This implies the background is missing and the style is not being applied somehow.

Steps To Reproduce

• Provide a code block in a markdown description

{% docs my_table_description %}
`My code block`
{% enddocs %}

• Generate and serve docs
• View markdown in provided docs

Expected behaviour

A blue background instead of white/none

Nice catch, @DVAlexHiggs, and thanks for opening this issue.

I was able to confirm that:

• This isn't an issue with inline code, only

code blocks

• It's an issue for code blocks whether defined in a docs bloc or inline in the .yml file
• In 0.16.1, code blocks are white text on a blue background. In 0.17.1, they are white text on a white background

I'm going to transfer this issue to the dbt-docs repo, since that's where we'll need to make the fix.
