如何选择网页字体?

一、如何设置网页字体大小

设置字体大小有两种方法:

第一种是使用CSS样式表中的font-size属性,例如:

body {
  font-size: 16px;
}

这样就会将整个页面的字体大小设置为16px。

第二种是在HTML标签中使用style属性,例如:

<p style="font-size: 14px;">这是一段14px大小的文字</p>

这样就会将该段文字的字体大小设置为14px。

二、如何将网页字体调大

可以使用上述中的方法之一,但需要将字体大小设置为比当前字体大小大的数值。

还可以使用JavaScript来改变字体大小:

function increaseFontSize() {
  var currentSize = parseInt(document.body.style.fontSize);
  currentSize = currentSize + 2;
  document.body.style.fontSize = currentSize + "px";
}

这个函数可以将body元素中的字体大小增加2px。

三、如何把网页字体缩小

可以使用上述中的方法之一,但需要将字体大小设置为比当前字体大小小的数值。

还可以使用JavaScript来改变字体大小:

function decreaseFontSize() {
  var currentSize = parseInt(document.body.style.fontSize);
  currentSize = currentSize - 2;
  document.body.style.fontSize = currentSize + "px";
}

这个函数可以将body元素中的字体大小减小2px。

四、如何让网页的字体和系统字体一样

可以使用font-family属性,例如:

body {
  font-family: "微软雅黑", Arial, sans-serif;
}

这样就会将页面的字体设置为“微软雅黑”,如果系统上没有安装该字体,则会使用默认的Arial字体或系统默认的sans-serif字体。

五、网页如何把字体变大

可以使用JavaScript来改变字体大小:

function increaseFontSize() {
  var currentSize = parseInt(document.body.style.fontSize);
  currentSize = currentSize + 2;
  document.body.style.fontSize = currentSize + "px";
}

这个函数可以将body元素中的字体大小增加2px。

六、网页如何调大字体选取

可以使用font-size属性或JavaScript来改变选取部分的字体大小,例如:

/* 使用CSS */
::selection {
  font-size: 18px;
}

/* 使用JavaScript */
function increaseSelectionFontSize() {
  var selection = window.getSelection();
  var range = selection.getRangeAt(0);
  var span = document.createElement("span");
  span.style.fontSize = "18px";
  span.appendChild(range.extractContents());
  range.insertNode(span);
}

第一种方法将会将选取部分的字体大小设置为18px,第二种方法将会将选取部分放在一个span元素中,并将该元素的字体大小设置为18px。
