I have template and page properties. I had added custom tab to page properties, where I need to modify the height and width of page property tab. How can I add custom styling to page properties. I using AEM 6.5 version.
Create a custom client library with custom styles and the category in page dialog. Refer below link, instead of js add css in your case.
Page property's dialog similar to the component dialog, create clientlibs and add using 'extraClientLibs' to page dialog.
@aditidwivedi What does it mean by " I need to modify the height and width of page property tab" is it like you want manage the height of the page properties tab while authoring ? Not any content on your page ?
