Working with SVG, like great browser support for SVG animation, means you get more capabilities to create brand new animation. Unlike HTML, there are still a lot of places on your website you can add new content. In addition to simply adding a few lines of text, you could add SVG files for custom icons, labels, buttons, and more. You can even use both the built-in SVG animation functionality and CSS3 animation (check that not everything can be implemented by CSS).The most straightforward way to add an element using SVG code is using the text element. Just place the desired text, or elements, on any web page and just use the SVG transform tool to add them to the page. There are even some cases where you can directly edit the element's properties using the keyboard's arrow keys, for example. These are just a few common features of working with animate on scroll animations.Another common feature that you can find when viewing SVG animations is the ability to define and add various attributes to your elements. For example, you can change the color of your stroke-dash array attribute easily simply by changing the color attribute's value from one number to another. Similarly, you can change the size of the stroke-dash array. These attributes, combined with the various effects that you can apply to each, allow you to get truly amazing results.Because SVG animations are based on canvas rather than HTML, there is also a plethora of other methods that you can use to animate your content. For example, instead of having to write long conditional statements in JavaScript, you can add simple CSS code on each frame of your animation. Likewise, instead of having to create a complex graphic or image object, you can create a path or draw function to instantly draw whatever it is you want in an element. Again, this allows you to add more element-based attributes and make your pages much easier to maintain.The final feature that makes SVG elements very appealing is the fact that they support the CSS Transform attribute, which allows you to animate the content by changing the initial value of the element. In the past, you would have needed to set up complex transitions or event handlers to handle this effect. Now, you can simply set the transform attribute's value to zero, which will result in the element automatically being drawn to a new style every time the source point changes.This feature is especially helpful for animating complex graphics such as logos or images. It allows you to draw a path and specify the coordinates of the center of the path, along with the direction you'd like the path to face. You can then use text attributes or JavaScript code to tell the browser where to place the destination point on the screen so that your logo is drawn exactly where you want it to appear. Finally, many browsers now support the Gecko rendering engine that is used in Safari and most Android phones. These browsers now have an infrastructure in place that allows them to efficiently render the SVG format, resulting in high-quality vector drawing commands for your site.
