Overview
SVG stands for Scalable Vector Graphics and is used to define graphics for the web using the XML format. It can be used for drawing paths, boxes, circles, text, and graphic images.
To create the SVG graphic, the <svg> element is used with a set width and height for the drawing area.
<svg width="500" height="500">
Sorry, your browser does not support SVG.
</svg>
Note
It’s good practice to include a line of text inside the <svg> element for those browsers that do not support SVG.
Once you have the canvas on the page, the SVG code is placed hat that will create the drawing. Here are a couple samples of the coding technique.
Drawing a Circle
<svg width="500" height="500">
<circle cx="250" cy="250" r="200" stroke="red" stroke-width="4" fill="yellow" />
Sorry, your browser does not support SVG.

Drawing a Rectangle
<svg width="400" height="200">
<rect width="400" height="200"
style="fill: rgb(255,0,0); stroke-width:4; stroke: rgb(0, 0, 0)" />

Drawing a Rounded Square
<svg width="500" height="500">
<rect width="400" height="400" x="50" y="20" rx="20" ry="20"
style="fill: rgb(255,0,0); stroke-width:4; stroke: rgb(0, 0, 0)" />

Drawing a Polygon Shape
<svg width="300" height="200">
<polygon points="100, 10 40, 200 190, 80 10, 80 160, 200"
style="fill: rgb(255,0,0); stroke-width:4; stroke: rgb(0, 0, 0)" />

Note
Most SVGs can be created in a vector editing program (like Affinity Designer or Adobe Illustrator) and output to an SVG, giving the image some major complexity, while keeping the coding to an absolute minimum.
HTML Notes:
- In our HTML section the term “tag” and “element” are often used interchangeably to refer to both the tag used to create a page element and the element created by the tag (<p> tag = <p> element = paragraph on the page)
- HTML5 is not case sensitive; so <P> is the same as <p>, <H1> is the same as <h1>
- Global attributes can be used with all HTML tags and are therefore not mentioned on every tag page
- To write clean, readable HTML code, it is best to use indentation whereas elements within elements are indented (tabbed or spaces) to create something that looks like a project outline
- The browser will automatically remove any extra spaces and lines in your HTML code when the page is displayed
- Double quotes or single quotes can be used around HTML attribute values, but when the attribute value itself contains one form of quote, it will be necessary to use the other around the attribute
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
