Is it possible to remove the banner strip (very thin image) from the blog page? Or if easier, show the slider on the blog page? I’ve looked in the dynamic settings of WidgetKit but the blog page isn’t listed.
The background image is actually done from Appearance >> Header. You can remove the image. As for showing the slider on the blog page, you can yes, and any other pages. Use a plugin called Display Widgets (easier to use than Dynamic Widgets) and publish the slideshow to your front page as well as the blog page. Are you using the Dynamic Widgets plugin?
