Answer 1

文本居中，但表单的宽度为 10/12(83%)。您应该将 col-md-10 更改为 col-md-12。

<div class="form-group">
    <div class="col-md-12">
        <input asp-for="Email" placeholder="Email" class="form-control" />
        <span asp-validation-for="Email" class="text-danger"></span>
    </div>
</div>
<div class="form-group">
    <div class="col-md-12">
        <input asp-for="Password" placeholder="Password" class="form-control" />
        <span asp-validation-for="Password" class="text-danger"></span>
    </div>
</div>
<div class="form-group">
    <div class="col-md-12">
        <button type="submit" class="btn btn-block">Sign in</button>
    </div>
</div>
