The edited version worked like a charm @Allon Prooit. Thank you for your kind help.

@Joseph Gatt - Sorry about that. I just uploaded an edited version that changes class="container" to class="icontainer" to avoid the system override this was causing. Let me know if this fixes the problem for you.

Post-script: However, for some reason, the new coding is messing the platform's layout. Whilst the layout is ok whilst the game itself is in play, I discovered that problems then mysteriously crop up afterwards. For example, on clicking the tab "Photos", you get a lot of white space on top. Also, in the welcome screen (i.e. before logging in into the platform), you also get a huge amount of white space, such that you have scroll down sharply in order to get to the logging interface. Because of these unexpected problems, I had to disable the component again, and now the layout is back in its original good shape.

Super! Many thanks @Allon Prooit !

It looks much better now.

@Arsalan - Many thanks for the suggestion. I was able to find advice at W3 Schools on how to do this. I altered the code for v1.5 some based on this. Now the iframes are responsive. Too small to work really well with mobile but, that's what the fullscreen buttons are for.
@Joseph - This should hopefully fix your problems with overlap. Check out W3 Schools for more ratios!

The problem seems is most of iframes in this component set the default height and width example

width="888" height="666"

Now this creates serious problem with responsive layouts. @Allon you may can search for responsive css iframes. I tried to find some references but there are couples so you can find on google that fits the need.

This is a very nice retro component.

Unfortunately, there is a snag. The game window is not sizing correctly, and the right portion of the game window is unfortunately covered with other components. (For the record, my display resolution is 1360 x 768.) I could send a screenshot, but it does not appear that this is technically possible within this thread.

Many thanks ~Z~ Man. I took your advice and shortened it some to get the special icons to show. Here's the code...

.menu-section-item-diablo:before {
content: url(<?php echo ossn_site_url('components/Arcade/images/diablo.png');?>) !important;}

Now I need to make some small adjustments to the icon placement to make it perfect! Any thoughts?

Yeah, you're almost done!
Change your css to

.menu-section-item-diablo:before {
    content: '' !important;
    background-image: url("<?php echo ossn_site_url();?>components/Arcade/images/diablo.png");
    background-repeat: no-repeat;
    height: 25px;
    width: 25px;
    margin-right: 7px;
}

Depending on the pngs you may have to twist the dimensions and margins a bit, but basically that's the way to address image icons.
And don't forget to remove your undefinded $icon lines from the com file - PHP8 will bomb out with a code like that.

Just uploaded a new version 1.4 with small code addition to show basic font awesome icons to the left of the games. Woohoo! Now, if someone can please help me make it show the special icons I made for the included games that would be awesome!
