I have generate a theme from the Chameleon
page and I noticed an issue with the upload component, the styling is not applied on the ‘browse’ button. I changed the styling back to Chameleon and the same problem happens.
Is this a known issue? Is there a solution? I could not find CSS information about the upload component in the book of Vaadin.
The upload elements () “Browser…” button is part of the native rendering of the browser, and is rarely affected by CSS. I’m not aware of any browser that would actually allow to style that element.
So I’m afraid it’s not possible to change the look of that particular button.
