## Divide and conquer

Creating a website is a hard task from the perspective of using your creative skills. Creating a full website is a larger task than what most people can fit in their brain at once. We may get overwhelmed at times.

Therefore, it is paramount to do some planning before designing the details. We used the principles of top-down design to position simple colored rectangles and not worrying about their contents. This way, we can avoid getting lost in the details.

It is a lot easier to create a contact form or a single blog post than to think about creating the whole website at once.

## Use cases of Flexbox

We used Flexbox for the following purposes: 

- Create a center-aligned and a right-aligned menu. 
- Create a header component including a logo on the left and a right-aligned menu on the right.
- Create a multiline container of six blog posts using the principles of responsive design.
- Create the layout of each blog post.
- Create a center-aligned form.

When you create a website, go through the same steps that you learned here to provide some structure for the creative process.
