Your suggestion doesn’t work. This is the section I see in Vileplume.css:
.cm-header-1.cm-header-1,
.markdown-preview-section.markdown-preview-section h1 {
font-family: var(--font-title);
font-weight: 400;
text-shadow: 1px 1px rgba(0,0,0,0.05),
2px 2px rgba(0,0,0,0.05),
3px 3px rgba(0,0,0,0.05),
4px 4px rgba(0,0,0,0.05),
5px 5px rgba(0,0,0,0.05),
6px 6px rgba(0,0,0,0.05),
7px 7px rgba(0,0,0,0.05),
8px 8px rgba(0,0,0,0.05),
9px 9px rgba(0,0,0,0.05)
}
Removing font-weight doesn’t fix it and there is no color reference.
I added your second code block to the bottom of the file and it doesn’t change anything either.
Am I editing the correct file?
