I use the Wordpress plugin to put hype exports into my website.
If I change slides It would be really helpful to change the underlying row color or image To match my content.
Is this possible?
I think I'd need to know more details about what you mean by "slides" and maybe you can give a test URL where this isn't what you want?
But without knowing more, my first question would be to ask if you've tried checking "Make background transparent" in the document inspector and then redoing the export?
First off, Hype itself only supports a single background color for the document. For embeds, it's usually better to add a rectangle the size of your slideshow in the background and set its color there. If you actually want to change the background color of the entire web page, there are also a few ways to do that by setting CSS via JavaScript.
Thanks, I will look into it.
