Let's say I go to a wordpress theme website in chrome browser and open a demo. I right-click on the page and choose inspect, then edit the elements of the page. I change some words, fonts, colors, image/logo urls, etc. and make it look clean for a potential client.
How can I save these changes I've made, and package them in such a way that the client could open the demo url in chrome, inspect, then load my changes to see what the product could look like should they decide to buy?
