I am new to WordPress. I am currently using version 4.9.12.
I have a static HTML website. I am converting this site into WordPress. Though I have created header.php, index.php, and footer.php files. My custom theme is ready. But I am now confused about my html static pages. I have some other html pages e.g. digital.html, seo.html. These pages has HTML plus a little css. Now what should I do for these pages? Should I create these static pages in WordPress dashboard (backend) or create separate PHP files named digital.php, seo.php etc.
In addition, I have a contact.html file too. This file has a form in it. So what should be right way to present contact form in WordPress. I want to retain my form and code. Should I create contact.php within my theme folder? Do I need to modify .htaccess file too to change url to mysite.com/contact?
