+
+The **`.querySelectorAll()`** method selects all elements in the DOM that match a given CSS selector. Unlike `.querySelector()`, which returns only the first matching element, `.querySelectorAll()` returns a static NodeList containing every element that meets the criteria.
+
+This method is essential for manipulating or interacting with multiple elements simultaneously. It enables operations like applying styles, adding event listeners, or updating content across several elements at once.
+
+## Syntax
+
+```pseudo
+document.querySelectorAll(selector);
+```
+
+- `selector`: A string containing one or more valid CSS selectors, separated by commas. These selectors can include class names, IDs, element types, attributes, and more.
+
+The method returns a NodeList of matching elements. Although a NodeList is not an array, it supports iteration with `forEach()` and can be converted to an array using `Array.from()`.
+
+## Example
+
+Given the following HTML structure for a todo list:
+
+```html
+
+
+
+ Todolist
+
+
+
+ - Go to the gym
+ - Read for two hours
+ - Call Jerry
+ - Take a nap
+
+
+
+```
+
+The following JavaScript code selects all `` elements with the class `item` and applies a blue text color to them:
+
+```js
+// Select all elements with the class "item"
+const items = document.querySelectorAll('.item');
+
+// Iterate over the NodeList and change the text color
+items.forEach(item => {
+ item.style.color = 'blue';
+});
+```
+
+In addition, to target only the `` elements with both `item` and `completed` classes, use this selector:
+
+```js
+const specialItems = document.querySelectorAll('.item.completed');
+
+specialItems.forEach(item => {
+ item.style.fontWeight = 'bold';
+ item.style.textDecoration = 'underline';
+});
+```
+
+These examples demonstrate how to use `.querySelectorAll()` to access and style multiple elements within the DOM.
