XD to HTML5 + CSS3
PSD to HTML is a common design-to-code process, converting a Adobe XD into an HTML file. This method allows web designers and developers to work together to make a great looking and highly functional website.
If you use the Adobe XD to HTML method, making a website mockup is the first step.
The design file is saved in .xd and later converted to HTML. This will transform a Adobe XD file to individual files which are used inside an HTML structure.
To put it simply, with the Adobe XD to HTML method, you take a stylized mockup and transform it into a functional site.
