3D Tetris game Blockout in JavaScript / HTML5

Hi.
I have found a source code in JavaScript/HTML5 to a 3D Tetris DOS game from 1989 called BlockOut.


Code:

Game:
http://ringdingcoder.github.io/CubeOut/

Now I have got help from fiverr to make it look like the original so now it looks like this.
Code:


Game:
https://jlivingstonsg.github.io/BlockOut/

I try to learn to code so now I have a question.
When I start the game page then there is no green level frame, down left.
It shows up first when I start the game and when a level get a cube then you get a cube with thats layers color.
But I would like to get the green frame to show up all the time, like in the original game.

I guess I am to look for some kind of “class” or “id” in the javascript code,
that stand for the green frame,
to paste in to the index.html , like this, I have in the index.html file.

                    <span class="speed_label_text">SPEED</span>
		<span id="rotSpeed" title="Change Rotation speed"> 

it is probably to look something like this

                   <span class="green_frame_down_left">GREENFRAMEDL</span>
		<span id="greenframe" title="green frame down left"> 

Am I on the right track?
