As per your code "question-title" is a css class which used in server side control and id of HTML control. So what are you trying to accomplish?

You can't have a hyphen in a server control's ID. You'll need to use CssClass="question-title" instead and update the css

.question-title,#question-title,#question-details,.taglist .input input {
	float: left;
	width: 82%;
}

I just tried it and it works fine, you probably haven't amended the text control or the css, or both.

<style>
.question-title,#question-title,#question-details,.taglist .input input {
float: left;
width: 82%;
}
</style>
<asp:TextBox ID="txtQuestionTitle" runat="server" CssClass="question-title" placeholder="title" />
