🔧 Technical Details

SVG Basic Syntax

Basic Structure:

<svg width="width" height="height" xmlns="http://www.w3.org/2000/svg">
  <!-- SVG content -->
</svg>

Common Elements:

• <rect>: Rectangle
• <circle>: Circle
• <ellipse>: Ellipse
• <line>: Line
• <polyline>: Polyline
• <polygon>: Polygon
• <path>: Path
• <text>: Text

Coordinate System

SVG uses Cartesian coordinate system:

• Origin (0,0) at top-left corner
• X-axis positive direction to the right
• Y-axis positive direction downward
• Default unit is pixels (px)

Style Attributes

Fill and Stroke:

• fill: Fill color
• stroke: Stroke color
• stroke-width: Stroke width
• opacity: Transparency

Text Styles:

• font-family: Font family
• font-size: Font size
• font-weight: Font weight
• text-anchor: Text alignment

💡 Tips & Tricks

• viewBox Attribute: Use viewBox for responsive scaling
• Group Elements: Use <g> tag to group related elements
• Reuse Elements: Use <defs> and <use> for element reuse
• Optimize Code: Remove unnecessary attributes and whitespace
• Accessibility: Add <title> and <desc> for better accessibility

⚠️ Important Notes

• Namespace: Ensure correct xmlns attribute is included
• Unit Consistency: Maintain consistent dimension units
• Browser Compatibility: Test across different browsers
• File Size: Complex graphics may result in large files
• Security: Avoid including malicious scripts in SVG
