Drupal 8.x

I am modifying Bartik into a new theme called Opal, and everything seems to work so far except for the search glyphicon "magnifying glass" symbol. It appears if I place my new theme back into 8.x core -- mysite.com/core/themes/opal -- but when I place my theme in the proper root directory, mysite.com/themes/opal, it disappears. Any advice would be most appreciated. I can always just spare the Opal folder in core when upgrading, but having it work in the proper folder would be better.   

I'm trying to add a toggle() with a slide function in my Drupal 8.5 theme and it's not working very well. I go to the browser console and see thousands of errors like this:

TypeError: r.easing[this.easing] is not a function.

Searching I find that it's likely because the easing plugin is not loaded. Looking at my page source I see many files being pulled in from /core/assets/vendor/jquery.ui/ui/* but nothing from /effects/ let alone /effects/slider

An unrecoverable error occurred. The uploaded file likely exceeded the maximum file size (40 MB) that this server supports.

Hi all!

I'm having trouble getting started with Drupal. I can follow a guide and make a Hello World website, but when I try to implement basic functionality I get stuck immediately.

We are building a Drupal 8 site for a government agency and use Oracle. Is anyone using Oracle as the database for Drupal 8? I would like to know if the Drupal 8 Oracle Driver is stable or if we should avoid this configuration. 

I saw that this project was a development version which makes me concerned that there will be a lot of issues.

I'm finding that I need to write some javascript to do media queries and find that the Modernizr library, which is included in core, is available to intelligently let me check the user's window size, etc. Usually when I try to learn a new library, I go to the browser console after reading some docs but find I cannot do so.

Modernizr.load is not a function
