Website for activity management

I would like to website for users where users can browse through some activities that they can participate in. Activity can be some outdoor group activity e.g biking Sunday, gardening etc . The overall theme of the website is focused more towards community based group projects where a group of people can host an event and others can browse through and participate or rate. The look and feel of the project revolves around feeling good as a community. Some key features that are required are as below 1. A "landing page" with branding, what we do and overview of trending activities 2. A "browse activity" page where all activities are listed in a grid or a list 3. An "Activity detail" page to view details of activity like what is it about, how many people are participating, comments section 4. "Login page" to view all your participating activities So basically its 4 core pages. Color combination can be anything of your choice and please propose your idea/concept first before starting any actual work. Concept can be in the form of screenshots or templates etc. Some clarification : You are only required to create the website template in the form of Html/Css (or some JS). I do not require any backend stuff to be made.
