引导数据库5具有vertical gutters for the Grid。不使用单独的行，而是将列放在单个rowdiv中。然后在行上使用您想要的gy-*...

  <form>
        <div class="row gy-4">
            <label for="inputEmail3" class="col-sm-2 col-form-label">Email</label>
            <div class="col-sm-10">
                <input type="email" class="form-control" id="inputEmail3">
            </div>
            <label for="inputPassword3" class="col-sm-2 col-form-label">Password</label>
            <div class="col-sm-10">
                <input type="password" class="form-control" id="inputPassword3">
            </div>
            <div class="col-sm-10 offset-sm-2">
                <div class="form-check">
                    <input class="form-check-input" type="checkbox" id="gridCheck1">
                    <label class="form-check-label" for="gridCheck1"> Example checkbox </label>
                </div>
