</https:></https:></https:></a><code>aria-current="page"<https:>属性标识当前激活的链接,但其位置会根据用户访问页面而变化。我们需要一种方法动态地为拥有该属性的<code><a><https:>标签添加<code>font-medium<https:>样式。<https:></https:></https:></code></https:></a></code></https:></code> <strong>Solution: <https:><https:>
</https:></https:></strong>The CSS property selector provides a solution. We can use <code>[aria-current="page"]<https:>选择器直接选中带有<code>aria-current="page"<https:>属性的<code><a><https:>标签,并设置其样式。<https:></https:></https:></a></code></https:></code></https:></code> The following CSS code can be implemented:<https:>
<pre class="brush:php;toolbar:false">[aria-current="page"] {
font-weight: 600; https://www.php.cn/link/58936a175470c7915a764a2e98ebacf3* or add class name: class="font-medium" *https://www.php.cn/link/58936a175470c7915a764a2e98ebacf3
}<https:>
<p>This code will make all with <code>aria-current="page"<https:>属性的元素字体加粗( <code>font-weight: 600<https:>相当于中等粗细)。 你也可以选择添加<code>font-medium<https:>类名,然后在你的样式表中定义<code>.font-medium { font-weight: 600; }<https:> 。 选择哪种方式取决于你的项目CSS结构和命名规范。直接设置样式更简洁,而使用类名则更易于管理和复用。<https:></https:></https:></code></https:></code></https:></code></https:></code> In this way, we can use <code>aria-current="page"<https:>属性动态地为导航链接添加样式,简洁高效地利用了HTML和CSS的特性。<https:></https:></https:></code> without JavaScript code to follow <code>aria-current="page"<https:>属性动态地为导航链接添加样式,简洁高效地利用了HTML和CSS的特性。<https:></https:></https:></code></p></https:>

在css中,可用list-style-type属性来去掉ul的圆点标记,语法为“ul{list-style-type:none}”;list-style-type属性可设置列表项标记的类型,当值为“none”可不定义标记,也可去除已有标记。

区别是:css是层叠样式表单,是将样式信息与网页内容分离的一种标记语言,主要用来设计网页的样式,还可以对网页各元素进行格式化;xml是可扩展标记语言,是一种数据存储语言,用于使用简单的标记描述数据,将文档分成许多部件并对这些部件加以标识。

在css中,可以利用cursor属性实现鼠标隐藏效果,该属性用于定义鼠标指针放在一个元素边界范围内时所用的光标形状,当属性值设置为none时,就可以实现鼠标隐藏效果,语法为“元素{cursor:none}”。

在css中,rtl是“right-to-left”的缩写,是从右往左的意思,指的是内联内容从右往左依次排布,是direction属性的一个属性值;该属性规定了文本的方向和书写方向,语法为“元素{direction:rtl}”。

在css中,可以利用“font-style”属性设置i元素不是斜体样式,该属性用于指定文本的字体样式,当属性值设置为“normal”时,会显示元素的标准字体样式,语法为“i元素{font-style:normal}”。

转换方法:1、给英文元素添加“text-transform: uppercase;”样式,可将所有的英文字母都变成大写;2、给英文元素添加“text-transform:capitalize;”样式,可将英文文本中每个单词的首字母变为大写。

在css3中,可以用“transform-origin”属性设置rotate的旋转中心点,该属性可更改转换元素的位置,第一个参数设置x轴的旋转位置,第二个参数设置y轴旋转位置,语法为“transform-origin:x轴位置 y轴位置”。
