can i build my project in another editor? and then save it by .html file and open tht in browser and copy paste the link to fcc solution?
Opening a html file in your browser doesn’t put it online. The “link” you would see would just be a reference to the location of the file on your own computer. The projects require that there is a live version of your project online. You can use a service like CodePen to do this for free.
