Bootstrap
- 웹 개발을 위한 오픈 소스 프론트엔드 프레임워크
HTML, CSS, JavaScript를 사용하여 웹 페이지 및 웹 애플리케이션을
쉽게 디자인하고 개발할 수 있도록 도와주는 도구 모음
즉 다른 사람이 만들어 놓은 css파일을 사용한다는 것
- Bootstrap 의 Grid 시스템은 12개의 컬럼(화면)으로 나눠져 있음
문서를 보고 전부 실행시켜봐야 함 → 간단한 토이 프로젝트를 만들어보기 → 정리하기

2. Grid Basic은 사용하지 말고 그냥 class를 하나 만들어서 grid 사용하기
flex는 사용하기
3. Color
여기 없는 색깔이 필요할 경우 style css만들어서 사용하기 → color.css만들어서 쓰면 됨
이름 짓는 규칙이 -이기에 충돌날것을 대비해서 -을 사용하지 않음
—이거나 _처럼 다르게 사용해야 충돌나지 않음
색의 공통 이름 primary : 다 파란색
sucess : 다 초록색
danger : 다 빨간색

<h2>Pagination</h2>
<p>To create a basic pagination, add the .pagination class to an ul element. Then add the .page-item to each li element and a .page-link class to each link inside li:</p>
<ul class="pagination">
<li class="page-item"><a class="page-link" href="#">Previous</a></li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item"><a class="page-link" href="#">2</a></li>

<p>In this example, the navigation bar is hidden on small screens and replaced by a button in the top right corner (try to re-size this window).</p>
<p>Only when the button is clicked, the navigation bar will be displayed.</p>
<p>Tip: You can also remove the .navbar-expand-md class to ALWAYS hide navbar links and display the toggler button.</p>
