How to retrieve textarea style features

I recently changed my to @hmtl.TextAreafor format. However, I still want to retrieve the Form style.

<textarea name="EmailId" style="width:50%; border-color: black" required>@Html.TextAreaFor(Model => Model.EmailID)</textarea>

I replaced this with

@Html.TextAreaFor(Model => Model.EmailID)

I still want to retrieve the style. Please help me with this.
