<form> <label for="fileUpload">Upload file</label> <input type="file" id="fileUpload" /> </form> CSS

input[type="file"]::file-selector-button { border: 2px solid #6c5ce7; padding: 0.2em 0.4em; border-radius: 0.2em; background-color: #a29bfe; transition: 1s; } input[type="file"]::file-selector-button:hover { background-color: #81ecec; border: 2px solid #00cec9; } Ergebnis
Beachten Sie, dass ::file-selector-button ein ganzes Element ist und daher den Regeln des UA-Stylesheets entspricht. Insbesondere werden Schriftarten und Farben nicht unbedingt von dem input-Element übernommen.
