HTML visual wonder with HTML5 Canvas

HTML5 Canvas element is a marvel that has allowed web designers to embed interactive visual images through HTML. With several attributes under its belt, it offers a result quite similar to real web software used in the preparation of images and dynamic animations.

How does it work?

A wide variety of methods and properties bring the web page to life using the canvas element. JavaScript is used to draw rectangles, fill gradients, and transform using scaling and rotation. Bézier curves and arcs can also be integrated to obtain the desired interface.

Like any image tag, the canvas element uses attributes such as width and height. Identification is required to identify it with JavaScript or any other programming language. Defining the canvas tag in this way draws an invisible layout on the web page. Style sheet elements such as border, background color, or margins help reveal a true-to-life image of the canvas on the screen. The default color is always black. Tags that use the color attribute can use RGB or hexadecimal values.

To create rectangles, the syntax fillRect (x, y, w, h) is used to make a rectangle on the screen, while strokeRect (x, y, w, h) defines the use of borders or strokes. fillStyle () and strokeStyle () set a shape with a specific color, pattern, and gradient. x and y are assigned coordinate values. Size values ​​are indicated by w and h. Multiple paths can be created with multiple strokes on the line by using beginPath () and closePath () at the beginning and end of the path. Like rectangles, diagonal or other gradients also have four arguments where the first two indicate the start point and the last two the end point of the gradient. However, the radial gradient uses six arguments where three arguments are for the circle from the start point and three are for the circle from the end point. To make a straight line, the moveTo () and lineTo () methods are used. To enter characters on the canvas tag, there are three attributes that can be used; font, textAlign, textBaseline To return an object to draw, use the getContext () method in which the 2d context method is more popular.

Canvas support!

The Canvas element is compatible with the latest versions of browsers and mobile devices such as Internet Explorer, Firefox, Safari, Chrome, Opera, iPhone and Android. In case some browser does not work with the canvas element, the fallback content is inserted inside the image tag between the opening and closing tags of the canvas. In other words, the fallback content is an image file that is displayed if the canvas element is not supported by a browser. JavaScript uses the syntax document.addEventListener (DOMContentLoaded) to load the page.

HTML5 Canvas element is mainly used for animations and moving objects. Rather, it is avoided to show static images. The dynamic output requirement every hour and every day of the year is driven by a canvas tag. Canvas tags are very commonly used on websites that run on JavaScript. Compared to Adobe Flash, it loads fast and has become the latest craze in the web world.
