VisuBezier

Provides a preview when hovering CSS easing functions in VS Code.

Features

Hover over any CSS easing function to get a preview of the animation, comparing it to a linear easing (default).

Extension Settings

This extension has a few settings:

• visubezier.defaulteasingfunction: Override the default comparison easing function with any valid easing function expressed as a keyword or a cubic-bezier() function (default: linear).
• visubezier.defaultduration: Override the duration of the animation with any valid duration expressed as 0.5s or 500ms (default: 1s).
• visubezier.defaultbackground: Override the background color for the preview area (default: #2d2d30).
• visubezier.defaultcolor: Override the foreground color for the preview elements (default: #d7d7d7).
• visubezier.defaultlanguages: Override the list of languages for which you want to activate the preview. (default: ["css","sass","scss","less","postcss","stylus","xml","svg"]).

Post-Install Sample

Paste this sample into VS Code after installing to see it in action:

button {
	transition-timing-function: ease;
	transition-timing-function: ease-in;
	transition-timing-function: ease-out;
	transition-timing-function: ease-in-out;
	transition-timing-function: cubic-bezier(0.4, -0.2, 0.42, 1.2);
	transition-timing-function: steps(7);
	transition-timing-function: steps(5, jump-none);
	transition-timing-function: steps(8, jump-both);
	transition-timing-function: steps(4, jump-start);
	transition-timing-function: steps(2, jump-end);
	transition-timing-function: step-start;
	transition-timing-function: step-end;
	transition-timing-function: ease, steps(3), cubic-bezier(1, 0, 0, 1);
}

Known Issues

• cubic-bezier containing any values other than pure numbers are currently ignored (e.g. calc() or var()).
• Points with negative values can cause the animation to fall out of the preview area.
