Hey Ismael

Thank you very much for your reply.
The LCP issue is gone, that was the next thing on my list :-)
My main concern is the CLS issue on desktop. Managed to fix it with 100vh height (i think) but since I have added the media query to have a different color section for IpadPro I can´t get rid of the bad CLS score. The 100vh solution makes the dektop version higher then 100vh and I am running out of ideas.

My CSS regarding this color sections:
 /* Color section container width and height  */

/* DESKTOP  */

.cjs-titel-keil-container .container {
  width: 100% !important;
  min-width: 100%;
  min-height: 80vh;
  padding: 0;
  margin-right: -1px;
  magin-top: -1px;   
}

@media only screen and (min-width: 1025px) {
.cjs-titel-keil-container-ipadpro {
  display:none !important;
}
}

/* IPADPRO  */

.cjs-titel-keil-container-ipadpro .container {
  width: 100% !important;
  min-width: 100%;
  padding: 0px;
  margin-right: -1px;
  magin-top: -1px;   
}

@media only screen and (max-width: 1024px) {
.cjs-titel-keil-container  {
  display:none !important;
}
}

Thank you for your Help
Best regards,
Christopher
