Do you want to add drop shadows to elements in your PowerApps without using images?
PowerApps does not provide an OOB property to set shadows for elements or controls but you can use the HTML text control to add html with custom styles to implement the desired shadow effect.
SVGs are another great way to generate custom icons, images, shadow effects, animations and much more. I love going the SVG route for animation effects and complex visuals as such. In this post we will walk through a simple html-css trick for adding effects to your app elements without the need for images.
