[opencms-dev] Image size inline in html widget

[Lorenz Lammersdorf]

Hi Atle,

I'm not sure which Tinymce image processing plugins are installed by 
Opencms, but you don't need to deal with Tinymce's config. Simply add

.mt-4 img {
   width: 1000px !important;
   max-width: 100%;
}

to /system/modules/org.klanen.core/resources/css/klanen.css

Regards
Lorenz
