How to change text color of a css class?
提问by el323
I am using Bootstrap.css, and there's a class named "form-control". I am using this class to style my aspx controls. The problem is that its textbox font color is grey and I want it to be black. I have no clue about CSS. Is there a way I can change that from grey to black? Thanks.

You can reset the text color of class - 'form-control' by adding
您可以通过添加重置类的文本颜色 - 'form-control'
.form-control {
color:#000000;
}
Add this property in a separate css file and include it just below bootstrap.min.css in head tag.
将此属性添加到单独的 css 文件中，并将其包含在 bootstrap.min.css 下方的 head 标记中。

You would need to add some code like this to your CSS file.
您需要将一些这样的代码添加到您的 CSS 文件中。
.form-control {
color: #000;
}
Keep in mind that you may have some specificity declaration issues. For example, if the color is set in bootstrap.css as a child of another element, you may not be able to override the color change unless you declare it with the parent as well. For example:
请记住，您可能会遇到一些特殊性声明问题。例如，如果在 bootstrap.css 中将颜色设置为另一个元素的子元素，则您可能无法覆盖颜色更改，除非您也将其声明为父元素。例如：
.parent .form-control {
color: #000;
}
You shouldn't be scared to learn some CSS though. It's very easy to grasp (you'll literally get the basics in less than an hour).
不过，您不应该害怕学习一些 CSS。它非常容易掌握（您将在不到一个小时的时间内掌握基本知识）。
