How To Build an Infinite Scroll Image Gallery with React and CSS Grid — step-by-step Javascript tutorial on Progressive Robot

How To Build an Infinite Scroll Image Gallery with React and CSS Grid

In this tutorial, we will use the React frontend Javascript framework and CSS Grid to build an infinite scroll image gallery, using the Unsplash API to embed the photographic images. Using a codepen coding challenge from Scotch.io as a base for our code, we will use React.js to build out the interface, Axios to make the HTTP requests, and the `react-infinite-scroll` library to implement the infinite scroll feature. Also, for this tutorial, we’ll employ React Hooks.

7 Ways to Reduce IT Deployment Costs in 2026

Gartner’s July 2026 forecast puts worldwide IT spending at $6.37 trillion, up 14.2 percent, while combined DRAM and SSD prices are expected to rise 130 percent by year end and push PC prices roughly 17 percent higher. Hardware got more expensive and budgets did not move, which leaves how many devices you deploy, how long they last, and what each deployment costs in labour, licence and rework. This guide sets out seven ways to reduce IT deployment costs in 2026 in the order they pay back: rationalising the hardware catalogue, buying against a forecast rather than a ticket, retiring imaging for zero-touch provisioning with direct despatch, automating application packaging and readiness testing, extending the refresh cycle on condition rather than calendar, making deployment the licence control point, and stopping the deployment of infrastructure nobody uses. It covers the unit that makes the comparison honest, where the seven ways conflict with each other, what the build-buy-rent decision actually turns on, the costs you should not cut, and the specific circumstances in which each mechanism fails.
