markdown fontsize config not having any affect in notebook

[jpmorr]

Description

In a jupyter notebook I can change the font size of rendered HTML tables by using the following command at the start of a notebook:
display(HTML("<style>.rendered_html table { font-size: 22px; }</style>"))

this does not work in jupyterlab so i went to advanced settings and tried changing the font size there:

    "codeCellConfig": {
        "fontSize": 14
    },
    "markdownCellConfig": {
        "fontSize": 44
    }
} 

Reproduce

1. Change fontsize
2. set cell type to markdown
3. edit cell (large font)
4. run cell to render -> small font

Expected behaviour

Increased fontsize for rendered markdown cells (tables, equations, etc)

Context

• Windows 10
• Chrome 78.0.3904.108
• JupyterLab 1.2.3

This is probably why the setting is called markdownCellConfig (with an emphasis on "Cell"), as it doesn't seem to control the rendered markdown. Is there a way to change to rendered cell's fontsize?

Currently, you can increase the font size of rendered markdown with a menu option:

Settings -> JupyterLab Theme -> Increase Content Font Size

There's a related setting in the Theme section of the Advanced Settings Editor.

Not the most intuitive setting, so I agree this deserves a rethink (along with the rest of our settings system). It may make sense to merge unrendered and rendered md font size into one setting

If your problem is not yet solved then I would like to add my answer. I recently found out that if you increase the "content-font-size1" in Jupyter lab's advanced setting then it will increase the font size of rendered markdown.

Just add this in the theme setting

{
    "overrides": {
        "content-font-size1": "16px"
    },

}

see the difference
