Greetings Marcel
There were two plugins that were causing problems. It did take me sometime to workout which plugins were the culprits and then to reorganise my website so they were no longer necessary.
I also changed the the site-description font-size from larger to inherit which made a big difference to the appearance.
/* To eat fully consciously connects us to the miracle of all life */
.site-description {
text-transform: none;
font-size: inherit;
}
Chrome, Firefox, Opera and Microsoft Edge are all presenting the website satisfactorily but very differently.
I have only just managed to get Text Resizer working again. I do not really know what I did that caused it to start working. It took much fiddling without really knowing what I was doing.
Thank you for your plugin. I suspect its apparent simplicity hides much detail.
Do you have a donation link?
