I have this layout with drag n drop upload on the left side.
My website is responsive but some tablets in landscape mode are large as computer screens. Smartphones and tablets can not upload images with drag n drop (which you see on the left side of the picture).
What I want to do is identify if the user visits my site from a tablet or smartphone. If it does, I want to hide the drag n drop feature and display only the upload button. But if the user is using a computer (even with small screen) I want drag n drop to be possible/visible.
Do not know which technology is required but my site uses HTML, CSS, JavaScript (jQuery) and PHP.
