Add css custom style specific to a page in wordpress
You can add custom styles to a specific page in wordpress without affecting the whole website.
Go to Appearance-> Customize->Additional CSS
.page-id-1047{
color:#000;/* add your custom css style code here*/
}
Here 1047 is the page id which you can get from the url when you edit the page:
For example,
…../wp-admin/post.php?post=1047&action=edit
Change page id as per your webpage, write custom css code and click publish.
