A full-screen SVG displays 100 horizontal stripes alternating in height across the viewport, with a circular mask revealing only the central region. The mask is defined as an SVG `<mask>` containing a white rectangle and a black circle, applied to each stripe via the `mask` attribute. The visualization uses raw DOM manipulation with `document.createElementNS` and `setAttribute` to construct the SVG elements dynamically in JavaScript, without any external libraries.

create mask

This example uses an SVG mask to create a circular window over a series of alternating horizontal rectangles. The mask, defined with an SVG `<mask>` element containing a white circle, is applied to each of the 100 rectangles via the `mask` attribute. The visualization demonstrates how SVG masks work in a bare-bones HTML page using vanilla JavaScript, dynamically creating the SVG elements and filling the viewport.

svg circle

This example renders 100 horizontal rectangles on an SVG canvas, with a circular mask applied so only the area inside a 200-pixel-radius circle centered on the screen is visible. The rectangles are spaced every 20 pixels vertically, each 10 pixels tall and spanning the full window width. The code creates the SVG elements using the native `document.createElementNS` API, building a mask containing a white circle and attaching it to each rectangle via the `mask` attribute. The visualization demonstrates basic SVG masking and procedural element creation in a browser environment.

design done

A grid of alternating horizontal and vertical striped rectangles covers the full screen, with a circular mask revealing an intersection of both orientations. The visualization uses raw SVG elements created via the DOM API, applying `mask` and `circle` elements to clip each stripe. A white circle in the first mask hides the horizontal bands except within its bounds, while the second mask uses a black circle on a white background to invert the effect for the vertical strips, producing a crisp radial pattern at the center.

SVG Fundamentals

This example demonstrates the visual impact of SVG masks, using them to selectively reveal or hide overlapping shapes. It creates a full-screen canvas filled with horizontal and vertical stripes by generating one hundred thin rectangles for each direction. A circular mask isolates a central area where the stripes remain visible, while a second, inverted mask produces a contrasting ring effect by revealing the vertical stripes outside the circle. The code builds the SVG document dynamically through the Document Object Model, creating elements like rectangles and masks using `createElementNS` and `setAttribute` within JavaScript.

svg mask

This example demonstrates the visual effect of SVG masks by layering horizontal and vertical stripes over a full-viewport canvas. It creates two circular masks, one with a white circle on a black background and the other with a black circle on a white background, then applies them to alternating sets of 50 thin rectangles. The code builds the entire scene programmatically using the Document Object Model (DOM) methods such as `createElementNS` and `setAttribute`, without any external libraries, and renders everything directly in SVG.

beginner svg

This example demonstrates a simple masking effect in SVG, where a set of horizontal stripes is revealed only through a circular window at the center of the viewport. The visualization uses plain SVG elements created dynamically via the `document.createElementNS` method. A white rectangle serves as the mask base, while a black circle defines the transparent region, and the stripes are drawn as individual `rect` elements with the mask applied. The code runs without any external libraries, relying purely on native browser APIs and JavaScript.

Fork of SVG Fundamentals

This example demonstrates SVG masking by layering a grid of horizontal and vertical rectangles over a circular cutout. The rectangles are created dynamically using the DOM API `document.createElementNS` with the SVG namespace. Two complementary masks, `circle-mask` and `circle-mask-2`, alternate between white and black fills to control visibility, producing a striped pattern inside the circle while keeping the surrounding area solid. The code relies on raw SVG manipulation rather than a visualization library, with only the `d3-selection` API imported but not actively used.

Untitled

This example renders horizontal and vertical alternating stripes masked by two circles in the center of an SVG canvas. The code uses raw SVG manipulation via `document.createElementNS` to construct masks, rectangles, and elements, with `d3` available as a dependency but not actively used. The first mask reveals horizontal stripes, while the second mask inverts the circle to show vertical stripes outside it, creating a crosshatched visual pattern that fills the viewport. The visualization demonstrates layered SVG masking techniques without data input.
