Font size cannot be updated

[hanweiqiao]

Hello,

I'm using teachPress to import publications into my webpage in WordPress. I'm using tplist to import from the database to the website. But the font size is little bit small for me so I want to make it bigger. I have tried to modify the style in WordPress Elementor, but only the color can be changed. When I adjust the font size of the tplist code it changes in the editor but not changing in the real webpage. I also tried to add

.tp_pub_title a {
	font-size: 20px !important;
}

into my style.css in WordPress dashboard but it still not changing. I also changed the Frontend styles to "your theme.css". Did I make anything wrong? Thanks!

Regards,
Han
