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 ... Read More
CSS inline-flex and inline-block are the values of CSS display property that are used to control how elements align and behave within their containers. When working on a responsive layout, the developer often needs to control how elements align and behave within their containers. Sometimes, we need elements to behave like inline elements but with some block-level properties, while at other times, we need more control over the alignment and spacing of children elements. This brings us to the comparison of two important CSS properties inline-block and inline flex. CSS inline-block and inline-flex Value of Display ... Read More
