AI-generated summary

This code is for a programming exercise where the background color of a webpage changes based on the parameters passed. The exercise went smoothly, but there are some areas where the syntax needs improvement. The code includes routes for the main page and two links, each with their own background color. The main page displays a blog title and the two links. The links lead to separate pages with different titles, blog dates, and texts. There is also a "Home" page that redirects to a different website.

Record#

Today is programming practice, adjusting the code for Day 77.
By passing different parameters, the background color is displayed differently.
Today's programming practice went smoothly. The thinking process was correct during the writing process, but there are still some areas where the syntax is not proficient and needs improvement.
