Source code: haoxiqiang-template Jekyll Overview Jekyll is a static site generator that converts plain text (Markdown, Liquid templates) into a complete static website without requiring a database. Combined with GitHub Pages, it provides free blog hosting. Features Code Highlighting Jekyll has built-in syntax highlighting powered by Rouge: 1 2 3 4 5 def print_hi(name) puts "Hi, #{name}" end print_hi('Tom') #=> prints 'Hi, Tom' LaTeX Math Rendering Set latex: true in the page front matter to enable MathJax rendering: $$ \begin{aligned} \dot{x} &= \sigma(y-x) \ \dot{y} &= \rho x - y - xz \ \dot{z} &= -\beta z + xy \end{aligned} $$ $$ a^2 + b^2 = c^2 $$ When $a \ne 0$, there are two solutions to $ax^2 + bx + c = 0$.
