Editing Files
If you don’t know anything about HTML and web pages, before doing anything with this template we recommend you to take at least some basic tutorial or hire somebody experienced to do this.
As for tutorials we recommend https://www.w3schools.com/. Editing php and JavaScript files is really advanced stuff, only experienced person should edit them. If you’re not sure, do not change anything, it might cause serious damage to the scripts. Hiring somebody, who knows what to do, is better solution.
If you are not familiar with these technologies, do not play around with these files.
