Page code:

<a href="select.html" rel="external nofollow" id="signId" class="btn btn-info" <span style="background-color: rgb(255, 255, 102);">target="dialog"</span> title=" Please select the type of meal "> Sign in </a> 

The modal box will pop up as long as you add target= "dialog" after the a tag and provide the href external link address
