Learnt a lot about Xara making this website: https://hypnosis-retreat.co.uk. Videos were edited in Lightworks, rendered through placeholders with tailored HTML/CSS. The WOW sliders were easy use and provide a great range of options. Editing the graphics in Xara worked well. SSL recognition with 1&1 hosting required a tailored .htaccess file to make the videos work on auto. Seems to work correctly on mobile too. Suggestions for improvement welcome.
