This article explores building a rudimentary 3D Minecraft-style world using only CSS transformations, HTML, and JavaScript, avoiding complex 3D programming. The author leverages their existing CSS knowledge, highlighting how concepts like z-index, left, and top already implicitly represent 3D space. The tutorial then delves into the power of CSS transformations, specifically transform-origin and transform, to achieve rotation, scaling, and translation in three dimensions.
The core of the project involves creating a JavaScript Block class to manage block creation and manipulation. Each block is constructed from multiple divs representing its faces, each positioned and rotated using CSS transforms. Texture mapping is implemented using a simple texture pack, adding visual realism.
The tutorial progresses to implement interactivity. Users can add blocks by clicking on existing block faces, with a "ghost" block previewing the placement. Viewport controls, including zooming via mouse wheel and rotation via mouse drag, are added to enhance navigation within the 3D space. Finally, the ability to remove blocks using modifier keys is introduced.
The article concludes by showcasing a fully functional, albeit simplified, 3D Minecraft-like editor built using this approach. It emphasizes the creative potential of CSS transformations for achieving 3D effects without the need for extensive 3D programming expertise. A companion article focusing on server-side persistence using PHP is also mentioned.

How to work with dates and times in js?
Jul 01, 2025 am 01:27 AM
The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
