<hr>
tag typically used for? / Alt.: What is the semantic
meaning of the <hr>
tag?<article>
.This is a confusing question and there can be an arguments for both the second and the third options being correct.
MDN: The HTML
<hr>
element represents a thematic break between paragraph-level elements.
Historically, this has been presented as a horizontal rule or line. While it may still be
displayed as a horizontal rule in visual browsers, this element is now defined in semantic
terms, rather than presentational terms, so if you wish to draw a horizontal line, you should do
so using appropriate CSS.

The <address> tag defines the contact information for the author/owner of a document or an article. The contact information can be an email address, URL, physical address, phone number, social media handle, etc. The text in the <address> element usually renders in italic, and browsers will always add a line break before and after the <address> element.

<input> elements of type checkbox are rendered by default as boxes that are checked (ticked) when activated, like you might see in an official government paper form. The exact appearance depends upon the operating system configuration under which the browser is running. Generally this is a square but it may have rounded corners.

100 (inclusive) in increments of 5<input type="range" min="0" max="100" by="5" />
<input type="range" min="0" max="100" step="5" />
<input type="number" min="0" max="100" step="5" />
<input type="number" min="0" max="100" by="5" />
<input> elements of type range let the user specify a numeric value which must be no less than a given value, and no more than another given value. The step attribute is a number that specifies the granularity that the value must adhere to.

; yesThe contenteditable global attribute is an enumerated attribute indicating if the element should be editable by the user. If so, the browser modifies its widget to allow editing. The attribute must take one of the following values: true or an empty string, which indicates that the element is editable; false, which indicates that the element is not editable.

<input> elements of type hidden let web developers include data that cannot be seen or modified by users when a form is submitted. For example, the ID of the content that is currently being ordered or edited, or a unique security token. Hidden inputs are completely invisible in the rendered page, and there is no way to make it visible in the page's content.

element's srcset
attribute should a browser on a small mobile phone load?<img
srcset="medium.jpg 320w, large.jpg 1280w"
src="small.jpg"
alt="Our favorite image"
sizes="(min-width: 1200px) 640px, 100vw"
/>
The browser will: 1. Look at its device width. 2. Work out which media condition in the sizes list is the first one to be true. 3. Look at the slot size given to that media query. 4. Load the image referenced in the srcset list that has the same size as the slot or, if there isn't one, the first image that is bigger than the chosen slot size.
