Read MoreFile Upload Example in Python
There are two common ways to upload a file using Python. One is through a cloud storage service using a web server, and CGI environment, (also known as an automated file upload system). In this tutorial, we will focus on file uploading using the CGI (Common Gateway Interface) environment. The process involves generating an HTML form for file uploading and a Python script to manage file saving and uploading to the server. The steps involved in uploading files using Python are as follows - Creating HTML Form ...

Read MoreNeumorphism Loading Spinner in HTML & CSS
In this article, we will create a Neumorphism Loading Spinner using HTML and CSS. The loading spinner is a common UI element used to indicate a process in progress, such as loading content or waiting for data from the server. We’ll add a modern touch to it using the Neumorphism design technique. Neumorphic designs give a 3D look by combining highlights and shadows around elements, making them appear to protrude or sink into the surface. Approach Let’s walk through the steps to create the Neumorphism loading spinner. Setting Up the HTML Structure We'll start by writing ...
