如何增加文本框的高度?(连同它的字体大小)

How do you increase the height of an textbox? (along with its font size)

推荐答案

我假设从您提出问题的方式来看,您想在页面呈现后更改大小?

I'm assuming from the way you worded the question that you want to change the size after the page has rendered?

在 Javascript 中,您可以操作 DOM CSS 属性,例如:

In Javascript, you can manipulate DOM CSS properties, for example:

document.getElementById('textboxid').style.height="200px";
document.getElementById('textboxid').style.fontSize="14pt";

如果您只是想指定高度和字体大小,请使用 CSS 或样式属性,例如

If you simply want to specify the height and font size, use CSS or style attributes, e.g.

//in your CSS file or <style> tag
#textboxid
{
    height:200px;
    font-size:14pt;
}

<!--in your HTML-->
<input id="textboxid" ...>

或者

<input style="height:200px;font-size:14pt;" .....>
