I have a quick customization question. Am updating the front page of this site. There's a lot to like about the Appolio template. But also some things to not like. The default layout has a position called masshead. It's pretty much the same thing as content-mast-top. Goes all the way across.
Except, the template suppresses the layout block below 768px on small devices.
In the template styles/responsive layout, this isn't supposed to happen. The extra-small layout shows the position as published and available to use.
It isn't.
I established that by running a test. I published a simple custom html module to my test page. Then I viewed it in smartphone emulation in Chrome and Firefox.
The module disappears.
It's because of a glitch in the code.
Both Firebox and Chrome point to a code sequence they identify as "masshead wrapper hidden-xs. "
The hidden-xs paramater can be found in Bootstrap. That's what's causing the issue. But I can't see how to fix it. I am hoping someone knows.
The template designer may have figured that nobody would want to use a masshead module on a smartphone. Well you can, with incredibly responsive apps like Nextend Smart Slider 3. It's really a super- sophisticated version of your custom html module.
So I do have the ability to scale elements all way down from HD widescreen to iPhone5 using the same layout block.
I'm asking if somebody can undo the code which is preventing the masshead layout block from publishing below the 768px mobile breakpoint.
Thanks as always to anyone who can assist!
