In web design, how to accurately determine the font size?

Generally, the font size of Chinese is 12px or 14px. As the resolution of monitors continues to increase, 12px text will look smaller on monitors larger than 1440*900, making it difficult to read. Therefore, 12px is now used less often in web design, especially in the body of articles. , 14px is generally used. The 13px font will have some display bugs under IE6, so it is not used too much now. However, as IE6 is gradually eliminated, this problem is no longer a problem. There are no special restrictions on the text size of the title bar, as long as it feels comfortable visually.

Font size code: font-size:14px (font size 14 pixels)
For font-family, generally speaking, text of 14px and below should be set to Song Dynasty, of course, it can also be set to Microsoft Yahei. However, there is no Yahei font by default under XP, so you can set the font in CSS like this:
font-family:"Microsoft Yahei",simSun,Arial;
Separate several fonts with commas. If If the system does not have the first font, use the second font. If the second font is not available, use the third font, and so on.
