+# getElementsByStyle
+
+Implement a method `getElementsByStyle()` that finds DOM elements that are rendered by the browser using the specified style. It is similar to `Element.getElementsByClassName()` but with some differences:
+
+- It is a pure function which takes in an element, a property string, and a value string representing the style's property/value pair to be matched on the elements descendants. E.g. `getElementsByStyle(document.body, 'font-size', '12px')`.
+- Similar to `Element.getElementsByClassName()`, only descendants of the element argument are searched, not the element itself.
+- Return an array of `Elements`, instead of an `HTMLCollection` of `Elements`.
+
+## Examples
+
+```javascript
+const doc = new DOMParser().parseFromString(
+  `<div>
+    <span style="font-size: 12px">Span</span>
+    <p style="font-size: 12px">Paragraph</p>
+    <blockquote style="font-size: 14px">Blockquote</blockquote>
+  </div>`,
+  'text/html'
+);
+
+getElementsByStyle(doc.body, 'font-size', '12px');
+// [span, p] <-- This is an array of elements.
+```
