I get stuck in there,please help me.I‘m sure the input is 10px,Why is this happening?


this issue is caused by your browser, you have a minimum font-size setting, do a google search:
change minimum font-size chrome
if you don't use chrome, change it with the browser you are using


The problem is solved.thank you very much! ! !


No need to change browser, just simply magnify your screen ~!
