CSS settings for LaTeX / Mathjax

In the default theme, and others as well, the font size of the equations are too small, smaller than the font size of the theme itself, while it should be equal.

It looks like this:

To fix this you could use the following snippet. Even when selecting different font sizes through the editor, the font sizes keep matching. (It could be that the 1.25 should be changed for some other themes.)

mjx-container { % works for live preview and reading mode
	line-height: 0px; 
	font-size: calc(1.25 * var(--editor-font-size));
}

The result is:

To make your notes look more like a LaTeX document you can use the following snippet:

mjx-container { % works for live preview and reading mode
	line-height: 0px;
	font-size: calc(1 * var(--editor-font-size));
}

/* reading mode */
.markdown-preview-view {
  font-family: 'CMU Serif Bold' !important;
}

/* source view and live preview */
.markdown-source-view.mod-cm6 .cm-scroller {
    font-family: 'CMU Serif Bold' !important;
}

Which will make it look like this:

It looks even better when using “justify” for text alignment:

/* reading mode */
.markdown-preview-view p {
	text-align: justify;
	text-justify: inter-word;	
}

/* source view and live preview */
.markdown-source-view.mod-cm6 .cm-line {
	text-align: justify;
	text-justify: inter-word;	
}
