Changed INF-306 Exam Questions

First box: minlength

Second box: maxlength

Third box: required

The correct validation attributes are minlength, maxlength, and required. The input must accept a category abbreviation that is either two or three characters long. The minlength= " 2 " attribute enforces the lower boundary by preventing submission when the entered text contains fewer than two characters. The maxlength= " 3 " attribute enforces the upper boundary by preventing the user from entering more than three characters into the field. Since the question states that the input is mandatory, the required attribute must also be included. required is a Boolean validation attribute, so it does not need a value; its presence alone makes the field required before the form can be submitted. Together, these attributes configure basic HTML5 constraint validation directly in markup without requiring JavaScript. The completed input therefore requires a value, rejects values shorter than two characters, and limits the value to no more than three characters.

The correct methods are setItem(), removeItem(), and clear(). The HTML5 Web Storage API exposes localStorage as a persistent key-value storage object for the current origin. Data stored in localStorage remains available after page reloads and browser restarts unless it is explicitly removed or cleared. setItem(key, value) stores a value under a named key or updates the value if the key already exists. removeItem(key) deletes one specific key-value pair from storage. clear() removes all key-value pairs from the storage object for that origin. These methods are part of the standard Storage interface used by both localStorage and sessionStorage. write is not a Web Storage method; it is associated with document-writing behavior, not application state storage. cookie is also incorrect because cookies are a separate browser storage mechanism accessed through document.cookie, not a method of localStorage.

First drop-down: four

Second drop-down: maxlength

Third drop-down: email, password, and phone

The form contains four user-entry input elements: email, password, confirm password, and phone. Since the requirements state that all fields must be completed, the required attribute must be applied to all four inputs. The password field must prevent entries longer than eight characters, so the correct length-control attribute is maxlength, not max; max applies to numeric/date-style value ranges, while maxlength limits character count in text-style inputs. The phone field also benefits from maxlength because its placeholder format has a fixed visible structure. Finally, completed pattern attributes are needed for email, password, and phone because each has a required format rule: the email must match the placeholder-style address format, the password must use only letters and numbers, and the phone number must follow the placeholder format such as 123-45-678. The title attribute should accompany these patterns to produce meaningful browser validation messages.

The correct answer is A. Applying float: right to an image removes the image from the normal inline flow and moves it to the right side of its containing block. Inline content, such as text, is then allowed to flow around the floated image. Because the image is anchored on the right, available text space is primarily on the left side of the image, and the text can continue above, beside, and below the floated region according to the surrounding layout. This is the classic use case for floating images within article-style content, where text wraps around a visual element rather than forcing the image to occupy an entire line. Option B is incomplete because it omits the important left-side wrapping behavior. Option C describes the opposite direction: an image floated left with text appearing to its right. Option D also describes float: left, not float: right. References/topics: CSS float, floated images, text wrapping, normal flow, content positioning.
