解説
問 60
- ア
正解 Responsive web design is a technique in which, for a single HTML document, CSS is used to switch the layout according to the screen size (screen width) and other characteristics of the displaying terminal, so that the content is shown in a way that is easy to view and easy to operate on a wide range of screens from PCs to smartphones. Option “ア” states that “the screen layout of the website changes according to the screen size of the displaying terminal,” which matches this definition exactly, so it is correct.
Incorrectイ
A mechanism that connects the user to a suitable server among multiple delivery servers to reduce the load describes a CDN (content delivery network), not a technique for fitting the screen layout to the terminal. It is unrelated to responsive web design.
Incorrectウ
Using data from the accelerometer and gyroscope sensors built into the terminal to measure step count and movement speed describes an app feature that uses the terminal's sensor API, not a technique that changes the layout according to the screen size.
Incorrectエ
Displaying explanations of functions or states in a popup when the mouse pointer hovers over the content describes a tooltip (balloon help), which is merely a supplementary UI display. It differs from responsive web design, which changes the layout for each terminal.
ここがポイント
- Responsive web design = a technique that changes the layout of the same page according to the terminal's screen size (screen width), so it is easy to view and operate on a variety of terminals such as PCs and smartphones.
- Distinguishing it from confusingly similar concepts: a CDN (optimal selection of a delivery server), use of terminal sensors (accelerometer, gyroscope), and tooltips (popup explanations on hover) are none of them responsive web design.
