This week, I learned to try to minimise the coding, try not to write code that is unnecessary. In addition, remember to convert symbols to HTML code. In order to let all users are able to read the contents without trouble.
I learned to use { box-sizing: border-box; } and found that it is easier to adjust the width what I want.
Reset CSS is also a good way to help me write my own CSS code. All the presentations can be dominated by our hands.
