![]() Unlike in HTML, we do not use background-color to set a color for a shape but we use the fill attribute.Īnd to set a border for a shape we use stroke and stroke-width. We also have presentational attributes that style our shapes. Remember, we moved the center of the coordinate system to the middle of the image and the X-axis grows to the right and the Y-axis grows towards the bottom. These positions are always related to the coordinate system defined by the viewBox. For the circle, we define the center position and for the rectangle, we define the top left corner. We'll position and style these elements with attributes. Let’s start with a simple Christmas tree ornament. How to Make a Christmas Ornament with SVG But don’t worry, there are similar tags available. HTML tags can’t be within an SVG tag, so we can’t have a div or a header tag inside an SVG. The same is true in the opposite direction. ![]() The SVG tag represents the frame of the image and every SVG element has to come within an SVG tag. While we can inline SVG images in an HTML file, that doesn’t mean we can freely combine any SVG tag with any HTML tag. The 0,0 coordinate will always be in the middle of the image. In this article, we will center the coordinate systems. Coordinates grow to the right and downwards. The first two numbers define which coordinate should be at the top left corner of the image. The viewBox also defines the center of the coordinate system in which the image items place themselves. Things appear bigger in this case, but the actual size of the image is still defined by the width and height property. In the last example we see what happens if the viewbox is focusing on only part of the image. The image simply shrinks down as all the coordinates and sizes defined within the image still align to the viewbox. ![]() In the first example we see what happens if the width and height are smaller. They appear quite different, though.Īt the example in the middle, the size defined by width and height matches the one defined by the viewbox. A circle element with the same center coordinate and same radius. In the next example we have three SVGs that have the very same content. The size defined by viewBox is how the image elements think of the image when they position themself inside of it. The size defined by width and height is how the rest of HTML thinks of the image and how big it appears in the browser. ![]() You can think of the width and height of an SVG as an external size and the viewBox as an internal size. These two can be confusing because they both define a size. This defines a coordinate system for the elements inside the image. There’s often a viewBox property as well. The width and height property define how much space the image takes up in the browser. It sets the inner size and the outer size of the image. This tag contains the image elements and defines the frame of our image. ( Watch this article as a video with even more fun examples.) The SVG tagįirst, we have to talk about the svg tag itself. So how do SVGs look like under the surface? In this tutorial, we go through the source code of a few SVGs to cover the foundations. But the next time you need a simple icon, a diagram, or animation, maybe you can code it yourself. Or we can turn things around and generate graphics from code.įor more complicated images, you will still use a designer tool. We can animate parts of an image from JavaScript or make it interactive. Suddenly we can access parts of an image from JavaScript or set the style from CSS. We can do this because SVGs have a very similar syntax to HTML. We can inline the code of an image right inside the HTML. We don’t even need to use the image tag that refers to a separate file. Since HTML5, we can include the code of an SVG image inside an HTML document. ![]() Well, good news – you can do all that and more without ever leaving your favorite code editor or using any third party tools or libraries. Have you ever needed an icon for your website, but you couldn't quite find the right one? Or perhaps you wanted to have a simple diagram, but didn't want to learn a whole new library just for that? ![]()
