Benchmark: Test: CSS calc() with var() - 01

HTML Preparation code:

<section id="section"></section>

Script Preparation code:

const section = document.getElementById("section");

section.style.setProperty('--translation', '100');
section.style.setProperty('--translationPx', '100px');
section.style.setProperty('--translationPercentage', '100%');


for (var i = 0; i < 1000; i++) {
    const newDiv = document.createElement("div");
    const text = document.createTextNode(`${i}`);
    newDiv.appendChild(text);
    section.appendChild(newDiv);
}

var nodes = document.querySelectorAll("div");

Tests:

var(unitless) + calc() + %
for (var i = 0; i < nodes.length; i++) { nodes[i].style = "transform: translateY(calc(var(--translation) * 1%))" }
var(%)
for (var i = 0; i < nodes.length; i++) { nodes[i].style = "transform: translateY(var(--translationPercent))" }
Percentage
for (var i = 0; i < nodes.length; i++) { nodes[i].style = "transform: translateY(100%)" }
var(unitless) + calc() + px
for (var i = 0; i < nodes.length; i++) { nodes[i].style = "transform: translateY(calc(var(--translation) * 1px))" }
px
for (var i = 0; i < nodes.length; i++) { nodes[i].style = "transform: translateY(100px)" }
var(px)
for (var i = 0; i < nodes.length; i++) { nodes[i].style = "transform: translateY(var(--translationPx))" }
