I have a very bizarre issue with Dreamweaver (version being used 2017.1). When I add the html5 line <source srcset="xxxxx.jpg" media="(min-width: 650px)"> some of the CSS formatting following the line is not displayed in the design view. The code is to load images responsively and is bracketed by picture tags eg <picture> <source srcset="xxxxx.jpg" media="(min-width: 650px)"> <img src="xxx-mob.jpg" alt="xxxxx" class="xxxxxxxx"> </picture> Following the guidance from: https://www.w3schools.com/tags/tag_picture.asp The design view acts normally before this line but after certain CSS effects are hidden. For example borders (around images), background images, border radius are just not seen. Margins. font sizes, colours and other formatting are displayed correctly. When I take out the offending <source> line everything appears normal. There are no errors and the page works fine in a web browser and also in live view (which takes forever to open). I’m confused but thanks for reading my question. Phil
