How to style SVG with external CSS?
To style an SVG with external CSS, assign classes or ids to your SVG elements, just like you would with HTML. In your CSS file, target these identifiers:
Use a <link rel="stylesheet" href="styles.css"> in the HTML head to link the CSS file. Your SVG will now sport these styles, leading to a unified design across HTML and SVG spaces.
Drawing vs Imaging: SVG Techniques
SVGs can either be integrated directly into your HTML as drawing elements or treated as images. The former allows you the flexibility to style SVGs using external CSS. However, when SVGs are embedded as images (<img src="image.svg">), they adopt inline styles bound within the SVG, overriding your external CSS.
The viewBox Magic Wand
In SVG, the viewBox attribute works like a magic wand for responsive design, ensuring your graphics scale well across devices. Combine it with CSS media queries for adaptability.
Jazzing Up SVGs with CSS and JavaScript
Pump up the interaction level of your SVGs with JavaScript, supporting dynamic style alterations. Let JavaScript create style elements with document.createElementNS and insert them into your SVG for real-time style revisions.
Stylebags: Internal, External, and Inline
When you need distinct styles for each SVG, go for an internal <style> tag. To apply dynamic styles from an external font across SVG objects, link an external CSS file using <link rel="stylesheet" type="text/css" href="styles.css">. For instant changes or effects, use inline styles but keep in mind, they stand first in line, overriding external and internal styles.
Styling with SVG symbols
SVG <symbol>s are reusable element blueprints. When influencing them externally, specific paths inside a symbol are off-target, but you can style each <use> instantiation.
Interacting with External SVG Files
Use <use xlink:href="path/to/svg#icon-name"> to reference external SVGs. This allows for efficient memory utilization. Be sure to predefine styles in your SVG definitions, as these won't take the CSS styles linked in your HTML file.
Color Transformations with CSS Filters
For simple color shifts, CSS filters like hue-rotate are a godsend. They're handy for icon theming or achieving a variety of visual effects without re-structuring your SVG.
Leveraging Tools for SVG Manipulation
Nokogiri for Ruby is a fine tool for programmatically updating SVG files. You can use equivalent XML libraries in other programming languages to inject styles or modify SVGs for precise external CSS styling.
Keeping SVG Functionality Intact
Preserving interactive features like tooltips or links is important. Keep your SVGs clickable and informative with meaningful <a> tags and style them to maintain both looks and functionality.
