Alex's woodworking shop is trying to design a web page with Cascading Style Sheets $($CSS$).$ Alex would like create the new design based on the latest elements and styles from Hypertext Markup Language $($HTML$)$ and CSS$.$ He has created a few sample pages:

$-$describes the business and contact information

product html $--$displays a list of product descriptions

custom html $--$displays a list of custom products

Alex's product style rules can be imported into a single file by adding the command

@import url $($css$.$product$)$;

@import css $($product$.$css$)$;

@import $($type: css url: product$)$;

$($aimport url $($product$.$css$)$;
