# --description--

|

|

|
|
CSS 裏面的 `top`、`bottom`、`left` 和 `right` 定義了元素在相應方位的偏移距離。 元素將從當前位置向屬性相反的方向偏移。 就像你在上一個挑戰看到的，`top` 屬性使 `h2` 向下移動。 同樣，使用 `left` 將項目移動到右邊。
|
||
|
|
|
||
|
|
# --instructions--
|
||
|
|
|
||
|
|
請通過 CSS 屬性把 `h2` 向上移動 10 像素，向右移動 15 像素。
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
應使用 CSS 屬性使 `h2` 相對當前位置向上移動 10px。 也就是說，從當前位置相對於 `bottom` 移動 10px。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert($('h2').css('bottom') == '10px');
|
||
|
|
```
|
||
|
|
|
||
|
|
應使用 CSS 屬性使 `h2` 相對當前位置向右移動 15px。 也就是說，從當前位置相對於 `left` 移動 15px。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert($('h2').css('left') == '15px');
|
||
|
|
```
