Blend landing page changes

1. the cards of documentation section should also be clickable right now only the arrows are interactive. The same interaction of scroll needs to happen on click of cards as well
2. The space is the playground card is not right, the text is too low
3. When I'm jumping from once section to another, the titles inbetween the sections are also getting highlighted on the navbar. Is that purposeful? - Reference
4. Both "Component" and the content for the connect with us section does not look centre aligned
5. Need to add the grids wherever applicable as per the design in the landing page
6. The buttons for the scroll also looks to bright, please check, I've added the design version as well. Same for the "learn more" and "connect with us" button, I think the stroke is either too opaque or the colour is off, those are standing out a lot - Reference
