const hasOne = new __helpers.CSSHelp(document).getStyle('.one');
assert(hasOne);

You should set the width property to 425px.

js
const hasWidth = new __helpers.CSSHelp(document).getCSSRules().some(x => x.style.width === '425px');
assert(hasWidth);

Your .one element should have a width value of 425px.
