Hi Forum

We are getting an error message when trying to create our own theme.

Please assist if possible.

The error message is below:

Error message

Warning: Invalid argument supplied for foreach() in Drupal\Core\Extension\ThemeHandler->addTheme() (line 125 of core/lib/Drupal/Core/Extension/ThemeHandler.php).

Dear Knowings,

I'd like to integrate a SVG-Image with inline Javascript to a node. The image is a map. When I hover a region of it, an explaining picture is shown. When I leave the region, the picture is unvisible. Therefor I need the script. It's generated in Inkscape with the function "plugins|internet|javascript|add attribute".

It's not the problem to insert the SVG with <svg> tag. I manged it with the module "svg image". So I am able to create a media SVG and insert it in the node as media. But the script-code is commented out. How can I prevent that?

I have a project I'm working on, but I've encountered a new situation. Usually with NPM, I just "NPM INSTALL [packagename]" and let it do its thing. But as I'm building my theme, I need that package to go to a particular location. I know with COMPOSER.JSON, I can use the "INSTALLER-PATHS" to point things where they need to go; but multiple searches on Google have come up bust, as far as PACKAGE.JSON is concerned. Can I just use "INSTALLER-PATHS", same as in COMPOSER.JSON or is there something different?

I would need a small help to get the output by adding the for loop. I have a view which has a image field. And I would like to theme it, I have created two view templates called "views-view-list--image-article.html.twig" and "views-view-fields--image-article.html.twig"

I want to achieve the output in the below format. Here "wrap clearfix" div is repeating and the inner divs "lhs-img" and "rhs-img" are also repeating.
