Styles from my index.css work incorrectly. More precisely, the styles specified by the standard HTML tags work, but, for example, I have id #contacts and the styles specified for it are not displayed even in chrome styles.
Here is the code: bootstrap connection

#contacts { font-family: monospace !important; } as a result, the font in the c id contacts does not change
