問題 #70
Which feature was introduced in HTML5?

A. Addition of CSS in the HTML file
B. Ability to hyperlink to multiple web pages
C. Adherence to strict XML syntax rules
D. Native drag-and-drop capability

答案：D

解題說明：
HTML5 introduced several new features that enhanced web development capabilities significantly. One of the notable features is the native drag-and-drop capability.
* Native Drag-and-Drop Capability:
* Description: HTML5 allows developers to create drag-and-drop interfaces natively using thedraggableattribute and the DragEvent interface. This means elements can be dragged and dropped within a web page without requiring external JavaScript libraries.
* Implementation:
* Making an Element Draggable: To make an element draggable, you set
thedraggableattribute totrue:
<div id="drag1" draggable="true">Drag me!</div>
* Handling Drag Events: You use event listeners for drag events such asdragstart,dragover, anddrop:
document.getElementById("drag1").addEventListener("dragstart", function(event) { event.dataTransfer.setData("text", event.target.id);
});
document.getElementById("dropzone").addEventListener("dragover", function(event) { event.preventDefault();
});
document.getElementById("dropzone").addEventListener("drop", function(event) { event.preventDefault(); var data = event.dataTransfer.getData("text"); event.target.appendChild(document.getElementById(data));
});
* Example: This example demonstrates a simple drag-and-drop operation:
html
Copy code
<div id="drag1" draggable="true">Drag me!</div>
<div id="dropzone" style="width: 200px; height: 200px; border: 1px solid black;">Drop here</div>

HTML5's native drag-and-drop feature streamlines the process of creating interactive web applications by eliminating the need for third-party libraries, thus making it a powerful addition to the HTML standard.

問題 #71
A web page includes the following CSS code:
```css
@keyframes anim_01 {
0% { left: 0px; top: 0px; }
50% { left: 200px; top: 0px; }
100% { left: 600px; top: 0px; }
}
.animation {
position: relative;
animation-name: anim_01;
animation-duration: 4s;
animation-timing-function: linear;
animation-iteration-count: infinite;
animation-direction: alternate;
animation-play-state: running;
}
```
What happens to the animation when the style is invoked?

A. It scales in size by 0% and then by 600%.
B. It moves horizontally across the screen.
C. It moves vertically across the screen.
D. It scales in size by 200% and then by 600%.

答案：B

解題說明：
> "The animation changes the `left` property from 0px to 600px while keeping the `top` at 0px throughout.
This means the animation causes horizontal movement only."
>
> "Since `position: relative` is set, changes in `left` and `top` move the element relative to its normal position." Thus, the element moves horizontally across the screen, alternating direction infinitely.

問題 #72
Given the following CSS statement:

Which code segment changes the font color when the viewport is 800 pixels wide or wider?

答案：C

解題說明：
To change the font color when the viewport is 800 pixels wide or wider, a media query withmin-width:
800pxis used. This ensures that the styles inside the media query are applied only when the viewport width is at least 800 pixels.
* CSS Media Queries:
* Syntax for Media Query:
@media screen and (min-width: 800px) {
body {
color: black;
}
}
* Explanation: Themin-width: 800pxcondition ensures that the styles are applied when the viewport is 800 pixels or wider.
* Example Analysis:
* Option A:
@media screen and (min-width: 800px) {
body {
color: black;
}
}
* Correct. This applies thecolor: black;style to thebodywhen the viewport is 800 pixels or wider.
* Option B:
@media min-width: 800px {
body {
color: black;
}
}
* Incorrect. Missingscreen andwhich is required for a proper media query targeting screens.
* Option C:
@media screen and (max-width: 800px) {
body {
color: black;
}
}
* Incorrect. This applies the style when the viewport is 800 pixels or narrower.
* Option D:
@media max-width: 800px {
body {
color: black;
}
}
* Incorrect. This applies the style when the viewport is 800 pixels or narrower.

The correct use of media queries ensures that the specified styles are applied only under the desired conditions, providing a responsive design.
