SVG and <image> tag tricks. По-русски A few days ago Lea Verou shared a link to Jake Archibald's post Having fun with <image> where he once again found out that image and img are nearly the same, all browsers replaceimage with img while parsing HTML.
A couple of months ago this property of image tag gave me the idea to use it for graceful degradation of SVG images in browsers which do not support SVG. The idea is extremely simple, we will have a SVG image for modern browsers and regular raster image for others. And write the following code: And here the magic: browsers which support SVG will read the code as: ignoring src attribute and will show SVG image. Browsers which do not support SVG will ignore unknown tag svg and thanks to image is replaced with img will read the code as: and will show regular image. For very simple images (e.g. icons), it is possible not to create a separate SVG file, just write all the content in HTML, that could be shorter than the file path. Visualización Básica de Gráficos SVG. Hay varias maneras diferentes de visualizar archivos SVG dentro de una página web.
La manera más sencilla es simplemente crear un enlace a un archivo SVG mediante la etiqueta <a>. Aquellos navegadores con capacidad de visualizar archivos SVG reproducirán el dibujo por separado en una página web. Para incluir un contenido SVG como parte de una página web se pueden utilizar cualquiera de las siguientes opciones: A continuación se describen cada una de estas opciones. Agregar SVG a una página web. En este tema, se presentan maneras comunes de incluir SVG en su página web.
View demo Download source One of the less talked about features of newer browsers is increasing support for the SVG file format. If you are unfamiliar with SVG, it stands for Scalable Vector Graphics. Unlike raster image formats like PNG, JPG or GIF, the vector graphics contained within SVG files are completely scalable to any size and will display at any resolution or screen density without quality loss. In many cases, SVG files will also be much smaller in filesize and download quicker. But one of the really cool things that some developers do not realize is that SVG is built on the XML specification, which at the end of the day means that its plain old markup, and can be worked with in a similar manner to HTML.
With the right techniques and modern browser support, developers can now produce some pretty impressive animations, effects and interactions using SVG. SVG Drawing Animation. A little experiment that explores the usage of SVG line drawing animations to precede the appearance of graphics or website elements, simulating the loading of them. View demo Download source SVG is finally becoming a more utilized and fun website component. It’s really powerful and there are many creative possibilities for fun effects on a website using SVG. Today we’d like to share two experimental concepts with you that make use of stroke animations, made popular by the animations on the PlayStation 4 and Xbox One review sites. This technique was introduced and explained by Jake Archibald in his article Animated line drawing in SVG and also explored by Brian Suda in his article Animating Vectors with SVG for 24Ways.
I like using diagrams as a way of showing information flow or browser behaviour, but large diagrams can be daunting at first glance. When I gave talks about the Application Cache and rendering performance I started with a blank screen and made the diagrams appear to draw themselves bit by bit as I described the process. Here's how it's done: Animating Vectors with SVG. It is almost 2014 and fifteen years ago the W3C started to develop a web-based scalable vector graphics (SVG) format.
As web technologies go, this one is pretty old and well entrenched. Embed not working on your device? Try direct. Unlike rasterized images, SVG files will stay crisp and sharp at any resolution. With high-DPI phones, tablets and monitors, all those rasterized icons are starting to look a bit old and blocky. I’m a big fan of SVG.
But, if SVG is so great, why doesn’t it get more attention? The simple answer is that for a long time it wasn’t well supported, so no one touched the technology. Although the browsers support SVG, it is implemented in many different ways.
