Hi Trang,
To achieve something like this, you will need to tweak the HTML structure of the Headline Block.
For instance, I have this Headline Block: https://share.getcloudapp.com/2Nuz0JW6
I added additional CSS class change-span-color
.
I then opened the Code Editor and inserted the text I wanted to change the color of inside a <span></span>
After this, I added this code:
.change-span-color span {
color: rgb(0, 0, 0);
}
Kindly replace rgb(0, 0, 0) with your preferred
color.
RGB selector: https://www.w3schools.com/colors/colors_picker.asp
Here is an article with regards to adding CSS: https://docs.generatepress.com/article/adding-css/#additional-css
Adding it through additional CSS should work.
Hope this helps! 🙂
