This article will introduce in detail how to set and use the transparency in the Canvas. Combined with incremental filling and transparency Support, the image Mask effect is achieved. The code of the linear progressive mode is demonstrated as follows, for more information about how to set and use parameters of progressive padding in HTML5 Canvas, and how to set and use opacity in Canvas, combined with incre

All beings with wisdom have survival skills, survival instincts, and desires for better survival. If you are a zombie, the hunters, the Downloaders, the climbing, the defender, and the defender are both. If you are a zombie, you can also count on her. If you are a zombie, you can count on her, even if the history books are right, they will be recorded as the myth of the century. The legend of the old man will surely be the legend of the story. Under the drive of the heart and possession, every

Describes how to set and use parameters for progressive padding in HTML5 Canvas, and how to set and enable transparency in Canvas. With incremental filling and transparency support to achieve the image's Mask effect. 1. Progressive filling (Gradient Fill) Canvas supports two progressive filling modes: Line Gradient Fill and Fill the radial gradient (RadialGradie

What is progressive enhancement (progressive enhancement), graceful demotion (graceful degradation)?Progressive Enhancement Progressive Enhancement: build pages for low-version browsers, ensure the most basic functionality, and then improve and append features such as effects and interactivity for advanced browsers to

Recently reading a Web experience related to the book "Progressive Enhancement-cross-platform user experience Design", read to do some summary, digest the essence of the book.Before reading this article, you can think about the following questions first.1. What is the purpose of browsing the Web?2. What problems will you encounter when browsing the Web?3. What are the ways to solve these problems?4. What are the specific implementation steps of these

In the previous article we made some basic introductions to progressive Web applications (PWA).Progressive web App (PWA) Getting Started tutorial (top)In this section, we'll show you what the principle of PWA is and how it began to work.First step: Use HTTPSAn incremental Web application requires an HTTPS connection. While using HTTPS can make your server more expensive, using HTTPS will make your site more

These two concepts are popular with CSS3,Progressive enhancement: Build the page for the lower version first to ensure the most basic functionality. Then optimize for a high-level version to improve the user experience.Graceful downgrade: Build the full functionality from the beginning and then be compatible with the low-version browser.GoThe "Graceful downgrade" viewThe "Graceful downgrade" view is that the site should be designed for the most advanc

The so-called "progressive attraction", nor what is not unprecedented after the new things, the author of this concept from a number of practical cases extracted, summed up as a product design and promotion of ideas, it is worth reference. Let's go, ba. What can you see when a user visits your product promotion page? It's usually a feature, a screen, a word of mouth. These, plus one or more action calls (call to action) operations. This kind of tradi

First, the common progressive loading picture modeCurrently we see the following three implementations of progressive loading:1) load different sizes of pictures from the web, from small to large. First pull a small thumbnail to do the stretching display, and then pull the medium-sized diagram, pull over the direct overlay display, and finally pull the original image, pull completed after the display of the

There is such a PMP test simulation question: Which of the following statements is incorrect:A. Scope spread is a function or service that is added without evaluating the impact on time and cost.B. Out-of-control changes usually refer to the spread of scope.C. There is no essential difference between scope spread and progressive details of functional requirements.D. Scope spread does not always increase customer satisfaction.The correct answer is C
