CSS not changing font size

Hello, I’m new to Supsystic and just install the Pricing Tables plug in. I noticed that the CSS editing feature does not change the font size. I’ve tried every size imaginable but nothing changes. I can however change some font families (not all for some reason), but I really need the font to be smaller, like the examples shown on your website.

Here is an excerpt. As you can see, font size is extremely small and line height is small as well, but table fonts are very big.

#{{table.view_id}} {
{% if table.params.calc_width.val == ‘table’ %}
width: {{ table.params.table_width.val }}{{ table.params.table_width_measure.val }};
{% endif %}
text-transform: none;
font-size: 2px;
padding: 8px 10px;
text-decoration: none !important;
border: none !important;
}
#{{table.view_id}} * {
line-height: 0.8em;
}
