Preview Image Before Upload in HTML CSS & JavaScript

In this program, at first, on the webpage, there is a file preview container with a cloud icon and an upload button. When you click on the choose a file button there will open a new window to select an image or file. After selecting the file, the preview of that file is shown on the preview container. And when you hover on the file, the name of that file will appear on the bottom side of the preview container. There is also shown a cancel button (cross-sign) and when you click on that button, the preview file which you selected will be hidden or canceled.

This program is only possible with the JavaScript files property. The file property returns a FileList object, describing the file or files selected with the file upload button. Through the FileList object, you can get the name, size, and contents of the files. This property is read-only.

Great tutorial! I appreciate how you broke down each step, making it easy to follow. The explanation of form validation is especially helpful, as it ensures user inputs are correct before submission. Best Preschools in Koramangala. Would love to see more examples like this for other types of elements. Keep up the good work!
