This problem involved the font settings of the computer and the display effect of the webpage. When the computer is online, the words displayed on the webpage may appear larger due to network delay or the response speed of the webpage server. This is because the webpage will wait for the server to respond after sending the request, which takes a certain amount of time. While waiting for a response, the webpage will use pre-loaded content to fill the page. These contents are usually some pictures, videos or other media files. The size of these files will directly affect the font size of the webpage. Even if the font size was set in the network option, it could not completely solve the problem of large font size. This is because the font size is only one aspect of the text size in the webpage. The webpage also uses other techniques to adjust the font size, such as font zooming, bold, and so on. Therefore, even if the font size changed the size of other content on the web page, it would also have an impact on the font size. If you want to make the text on the webpage look smaller, you can try using some browser plug-ins or adjust the webpage's CSS-style to adjust the font size. For example, you can use the font-size property of the SSS to set the text size or use some browser plug-ins such as the font manager to automatically adjust the font size.
