This tips is only from my opinion, just wanna share it with other.
All content in slider must be attractive so that reader/or verifier interested to read
What things need consider is :
1. Choose background color must be contrast with font color.
2. Size of font not to small and the type of font is easy to read. click here for example
3. Animated in your blog also will consider, reduce as long as you can but sometime animate is important at right place.
4. The important things is your word, not too long, simple and straight to what you want story
