The correct positioning method is static. In CSS, position: static is the default positioning behavior for elements. A statically positioned element remains in the normal document flow, meaning it is laid out according to the order of the markup and directly follows preceding elements unless another layout rule changes that flow. MDN defines static positioning as placing the element according to the normal flow of the document, with top, right, bottom, left, and z-index having no effect. This matches the requirement that the element always directly follows the previous default-positioned element and does not depend on viewport characteristics. absolute removes the element from normal flow and positions it relative to a containing block. fixed also removes it from normal flow and positions it relative to the viewport. sticky starts in normal flow but changes behavior relative to a scrolling ancestor when a threshold is crossed.

First blank: < svg width= " 200 " height= " 200 " >

Second blank: < rect width= " 200 " height= " 200 "

Third blank: < circle cx= " 100 " cy= " 100 " r= " 50 "

Fourth blank: < /svg >

The correct solution uses SVG because SVG graphics are vector-based and can scale without pixel distortion when the page or viewport changes. A < canvas > element would require script-based drawing logic, which violates the requirement that JavaScript must not be required. An < img > or < picture > element can display an image, but those options do not define the rectangle and circle directly in markup. The outer container must therefore be < svg width= " 200 " height= " 200 " > . The blue square is created with < rect width= " 200 " height= " 200 " fill= " blue " / > , which produces a rectangle matching the required 200-by-200 dimensions. The centered white circle must use SVG circle geometry: cx= " 100 " and cy= " 100 " place the center at the midpoint of the 200-by-200 square, and r= " 50 " creates the required 50-pixel radius. The final closing tag must be < /svg > .

The valid selections are mouseup, scroll, and blur. A < canvas > element is represented by HTMLCanvasElement, which inherits from HTMLElement; therefore, it participates in the normal DOM event model for element-based interaction. mouseup is valid because it is fired on an Element when a pointing-device button is released while the pointer is over that element, which is a common canvas interaction pattern for drawing tools, games, drag tracking, and selection behavior. scroll is valid as an element event when an element is scrolled, and the HTML event-handler index lists onscroll for HTML elements. blur is also valid because it fires when an element loses focus; a canvas can participate in focus workflows, particularly when made focusable with attributes such as tabindex. play is excluded in this certification context because it is a media playback event associated with HTMLMediaElement behavior, not canvas graphics interaction. datareceived is not a standard HTML canvas or DOM event.

< h1 > The Fitness World Around Us - Spring Conference < /h1 >

< form action= " process.php " method= " post " >

The correct solution must satisfy all three stated form requirements. The title " Conference Registration Form " is supplied by the < legend > element in the first valid code segment. That same segment also includes the required attendee name field by using a < label > associated with an < input type= " text " > . The for= " name " and id= " name " relationship makes the label programmatically connected to the input, which is the correct HTML form-accessibility pattern. For the food options, the correct choice is the segment that uses an < input > element with a list attribute connected to a < datalist > element. This is required because the attendee must be able to select an option by using the mouse or type a value manually. A < select > element provides a fixed dropdown list, and radio buttons provide fixed clickable choices, but neither is the best match for a type-ahead list requirement. The < datalist > element supplies predefined options such as Vegetarian, Traditional, and Surprise Me while still allowing keyboard entry through the associated input field.
