Imaging .blog-dynamic-content
is a name you give to the container block which holds the text (dynamic content block).
So in the effect, we set:
1. In normal state of the parent container, the .blog-dynamic-content
is set to transparent (opacity: 0;
).
2. In the hover state of the parent container, the .blog-dynamic-content
is set to show (opacity: 0.9;
).
