[LayaAir3]请问web版本如何让游戏运行在特定的标签下

<main role="main" id="main" class="main" style="height:100%;padding-left:0">

    <div id="ga_game" style="height:100%;position:relative;">

        <!------- GAME BODY SPACE START --------->

        <iframe src="http://game.abc.com/" 

                style="width: 100%; height: 100%; border: none; position: absolute; top: 0; left: 0;">

            Your browser does not support iframes.

        </iframe>

        <!--------- GAME BODY SPACE END ---------->

    </div>

</main>
