Vue.js是一款非常流行的前端框架，是一種輕量級的MVVM框架。它基于HTML和JavaScript，易于學習和使用。Vue.js由中國的Evan You創(chuàng)建，并于2014年正式發(fā)布。

Github provides a free static site hosting service called Github Pages. This service makes it easy to create a website, blog or portfolio. Vue.js can be used to create these types of websites. Github Pages allows you to host a static website from your github repository.

If you want to use Github Pages to host your Vue.js website, you will need to create a github repository for your website. You can create a new repository and name it 'username.github.io'. Once you have created the repository, you can commit your Vue.js code to the repository using git commands. Once you have committed your code, you can access your website at 'https://username.github.io'.

git init
git add .
git commit -m "First commit"
git remote add origin https://github.com/username/username.github.io.git
git push -u origin master

If you want to use a custom domain name, you need to add a CNAME file to your repository and configure your domain's DNS settings to point to Github Pages. You can also use a custom theme for your Vue.js website by creating a new repository and committing a theme's files to it.

In conclusion, Github Pages is a great way to host your Vue.js websites online for free. It is easy to set up and provides a professional look to your websites. With a custom domain name and theme, you can create a unique and professional website that showcases your skills and portfolio.
