The given code snippet demonstrates how JavaScript can manipulate the DOM to change the style of an element.
* Code Analysis:
* Given the HTML:
<h1 id="id1">Blog Title</h1>
<button type="button" onclick="document.getElementById('id1').style.color = 'red'">Click Here</button>
* When the button is clicked, the JavaScript code within theonclickattribute changes the color of theh1element to red.
* Explanation:
* Option A: An event handler tracking keyboard strokes is incorrect because the event handler is tracking a mouse click, not keyboard strokes.
* Option B: JavaScript is using the DOM to make a style change is correct because theonclickattribute contains JavaScript code that modifies the style of theh1element.
* Option C: In-line CSS is styling the<h1>tag is incorrect because the style change is done via JavaScript, not inline CSS.
