Changing button color for "reply to customer" button on issue

[Haseeb Khan]

I tried injecting this script

<style type="text/css">
button.aui-button.aui-button-primary.sd-external-submit {

background-color: #d04437
</style>

in the announcement banner with no change. I tried playing around with other setting on the announcement banner and they do make changes happens ( visible banner, color etc). Do I need to look into the button attribute name for it to take affect?

Hi @Haseeb Khan

On the Cloud products it is not possible to use custom CSS. 

Also see this post: https://community.atlassian.com/t5/Jira-questions/Custom-CSS-in-Jira-Cloud/qaq-p/1471186 

On Data Center you can, but not in Cloud. 

Kind regards, Rik
