Define and Explain the DOM
The DOM stands for Document Object Model. It represents the objects, structure, and content of an HTML file. The DOM makes the model of the HTML page and accesses it to show what a person sees when the page loads on the browser. The DOM also has several elements that can be accessed by using different queries in the page's Javascript file to change the appearance of the page in the browser.
DOM Specifications
W3C seems to be the leader in setting DOM specifications and recommendations. The DOM specifications from a W3C website page outline all the different ways the DOM can be accessed, HTML requirements for the DOM, how the CSS file interacts with it, and more.
DOM Implementation in Browsers
Browsers render the DOM by creating a model of the page called the DOM tree. The DOM tree is different depending on all the different elements included in an HTML file. The DOM tree is then stored in the browser's memory. There are several different types of queries that can be used with the DOM in the Javascript file such as getElementById and getElementsByClassName which can change the orignal appearance of the HTML code.
Summary
Overall, the DOM is a complex structure that represents the overall HTML file and has specific requirements set by W3C. The javascript file can include queries to access the DOM and change the appearance of how the browser renders the page.
