Reusing Graphical Objects from Symbols | SVG

Symbols are reusable graphical objects that can be defined once and then used multiple times within a design. They are particularly useful for creating complex or repetitive elements that need to be consistent across a website.

Creating Symbols

1. Design the symbol: Create the desired graphical element in your design software.
2. Save as a symbol: Export the element as a symbol format supported by your design software.
3. Import the symbol: Import the symbol into your web design project.

Using Symbols in SVG

• <symbol> element: Define the symbol within your SVG file.
• <use> element: Use the href attribute to reference the symbol.

Example:

HTML

<svg width=”300″ height=”300″>

  <symbol id=”my-symbol”>

    <circle cx=”50″ cy=”50″ r=”25″ fill=”blue” />

  </symbol>

  <use xlink:href=”#my-symbol” x=”50″ y=”50″ />

  <use xlink:href=”#my-symbol” x=”150″ y=”50″ />

</svg>

Benefits of Using Symbols

• Consistency: Ensures that elements are consistent throughout your design.
• Efficiency: Reduces the amount of code needed to create multiple instances of the same element.
• Maintainability: Makes it easier to update elements across your design.

Responsive Considerations

• Use relative units: Use em or rem for dimensions to create responsive layouts.
• Consider scaling: Adjust the size of the symbol using the width and height attributes or CSS transformations.
• Test on various devices: Ensure that the symbol looks and behaves as expected on different screen sizes and orientations.

Additional Tips

• Organize symbols: Group related symbols into separate SVG files for better organization.
• Use a design system: Create a design system that defines reusable symbols and components.
• Leverage SVG libraries: Explore libraries like Iconify or Font Awesome for pre-made SVG symbols.

By effectively using symbols, you can create more efficient, consistent, and maintainable web designs.
