How and where should i change background colour and text colour

my issue with text at

i have created using gitlab pages jekyll

my repo

thank you

you just need to edit your css, the way you have it I assume you are talking about the white box with white text that is hard to read, that is inside a <code> block, so you could edit the css for that element to change the color and the background-color.

i found solution partially in _base.scss.
i am at loss how to change the text colour though in code block.

its just css, google has a never ending amount of info. But if you find the code element, color: red; should do it.

If you open the inspect the block of code is added like:
“< code class=“highlighter-rouge”>a straightforward person</ code>”

Find the code tag and the class and style them they way you’d like.
