Bug 104821 – [CSS Grid Layout] element.style.webkitGridRows / webkitGridColumns doesn't return the right value

• Status: RESOLVED
• Resolution: WORKSFORME
• Component: CSS

[Julien Chaffraix]

If you try to get back the grid-rows / grid-columns from JS using Element.style, the values are not right. For example, with minmax:

element = document.createElement("div");
document.body.appendChild(element);
element.style.font = "10px Ahem";
element.style.webkitGridColumns = "minmax(22em, 8vh)";
element.style.webkitGridRows = "minmax(10vw, 5em)";
alert(element.style.webkitGridColumns); // "22em 8vh"
alert(element.style.webkitGridRows); // "10vw 5em"

It's unclear to me what we _should_ return though but those are definitely wrong. Also we have no coverage for getting back using Element.style which explains why we missed it. Whoever takes this bug should ensure a good coverage for most scenarios.

This was already fixed and properly covered by multiple tests. Just to mention some
