Note: I’ll be breaking down all of them, but not all at once....

HTTP headers let the client and the server pass additional information with an HTTP request or response....

In this blog post we will look into how we can add a Zoom-In effect for better visibility. We will be using Markdown Render Hooks from Hugo with HTML & CSS, implementing a non-javascript solution. View the outcome 👇 About Markdown Render Hooks Hugo offers really handy Markdown Render Hooks. These allow custom templates to override markdown rendering functionality. We will be using render-image hook to process out the images in the post as per our needs....
