Fonts and visual appearance of chat

[sibawal]

People, is it possible to somehow make the font and color the same as in a regular telegram chat?
Now it looks like this

But I would like to make it simpler, like regular correspondence.

Where are the font settings?

Понял что пропустил вопрос... Наверно уже не актуально, но:
Forgot about question... Perhaps its too late, but answer is:
conf.py

    html_tag = Field(default=["<pre>", "</pre>"], description="html tags for ordinary text")
    translate_html_tag = Field(
        default=['<span class="tg-spoiler">', "</span>"], description="html tags for translated text"
    )
