# Wireframing in HTML and CSS
Designers refine sketches into HTML and CSS wireframes. HTML and CSS wireframes are built using Design Block in the browser so the team can understand the core experience as fast as possible. It also allows developers to start implementing features within the wireframes.
It is crucial to keep the design of the application ahead of the development. Focus should be placed on wireframing usability, user experience, and flows.
We find it important to keep the design and development cycle adequately tight. We do not wireframe one month out because as we approach certain areas of the product, we often decide to cut or change features.
Those changes are an expected part of the iterative process and feedback loop between the client, the CodeCarrot team, and users. It would be wasteful to spend time wireframing features that never get built or building features that won't be used.
