SVG stands for Scalable Vector Graphics and is a powerful XML-based markup language for describing two-dimensional vector graphics. It is a web standard that enables the creation of resolution-independent graphics. Unlike raster images (such as JPEG or PNG), SVG graphics maintain quality even when zoomed or resized and SVG images are resolution-independent, meaning they can be scaled to any size without losing quality. This makes SVG an ideal choice for web design, graphic design, and data visualization. SVG is supported by all major browsers.
In this SVG tutorial, we'll learn all topics of SVG such as transformations, animations, and interactivity, mastering the art of creating dynamic and visually stunning graphics for the web.
What is SVG?
SVG is an acronym for Scalable Vector Graphics. It is used on the Web to create vector-based graphics. The graphics are defined in XML format, and each element and attribute in SVG files can be animated.
SVG is recommended by W3C and can be integrated with other standards such as CSS, DOM, XSL, and JavaScript.
Why Learn SVG?
- Dynamic Graphics: SVG allows developers to create interactive and dynamic graphics, enhancing user interactivity. It is particularly useful for data visualizations, interactive maps, and other engaging web elements.
- Smaller File Size: SVG images have smaller file sizes compared to raster formats, resulting in faster website loading times.
- Browser Compatibility: SVG is compatible with most modern browsers, ensuring consistent rendering across different platforms.
- Integration with HTML & CSS: SVG seamlessly integrates with HTML and CSS, allowing developers to create complex and responsive design layouts.
- Versatility: SVG supports various types of graphics, including icons, logos, charts, and maps.
How SVG Integrates with HTML?
There are several ways to use SVG within HTML:
- Inline SVG: Embed SVG directly within HTML using the
<svg> element. - External SVG: Link to an external SVG file using the
<object> or <img> element. - SVG as CSS Background: Use SVG images as backgrounds with CSS.
- Inline SVG with
<use>: Reuse SVG elements within HTML using the <use> element. - JavaScript Manipulation: Dynamically create or modify SVG elements using JavaScript.
SVG Examples
In this example, we demonstrates an inline SVG example, showcasing a red circle created using the <svg> element.
