You can't do this insidea <textarea>, not one that's editable. It sounds like you're after a WYSIWYG editor, most of which use a <iframe>to do this.
你不能在一个<textarea>，而不是一个可编辑的里面做这件事。听起来您在使用WYSIWYG editor，其中大多数使用 a<iframe>来执行此操作。
There are several JavaScript options for this, to name a few:

You cannot do this with a textarea or input tag. However, as @naikus mentioned, you can use the contenteditable attribute. It is as follows:
你不能用 textarea 或 input 标签来做到这一点。但是，正如@naikus 提到的，您可以使用 contenteditable 属性。如下：
<div id="mytxt" contenteditable="true">
Hello, my name is <span style="color: blue;">Bob</span>
and I have a friend name <span style="color: green;">Joe</span>.
</div>
<div id="mytxt" contenteditable="true">
Hello, my name is <span style="color: blue;">Bob</span> and I have a friend name <span style="color: green;">Joe</span>.

I don't think its possible to do that with a textarea and html alone. What you need is a Rich Text box You can either roll your ownby modifying an iframe, or use the popular ones available
我认为单独使用 textarea 和 html 不可能做到这一点。你需要的是一个富文本框你可以通过修改一个 iframe来滚动你自己的，或者使用可用的流行的
Other option you can have when you target html5 enabled browsers is the contentEditableattribute. You can use it to make a textbox-like control
当您定位支持 html5 的浏览器时，您可以拥有的其他选项是contentEditable属性。您可以使用它来制作类似文本框的控件

This is not possible in a normal textarea.
这在普通的 textarea 中是不可能的。
For syntax highlighting-like approaches, see the answers to this question.
For a more complicated, full-fledged WYSIWYG solution that can do colours as well as other formatting, images, etc., see a WYSIWYG editor like CKEditor.

You can't do this with default html controls. You can use Rich Text Box editors to get what you want, for example check this question:
您不能使用默认的 html 控件执行此操作。您可以使用富文本框编辑器来获取您想要的内容，例如检查这个问题：

That's not possible with current w3c specs. If you're looking for a workaround, check codemirroror editAreafor their workarounds for syntax highlighting.
这在当前的 w3c 规范中是不可能的。如果您正在寻找解决方法，请检查codemirror或editArea以获取语法突出显示的解决方法。
