Jekyll supports the use of Markdown with inline HTML tags which makes it easier to quickly write posts with Jekyll, without having to worry too much about text formatting. A sample of the formatting follows.

Tables have also been extended from Markdown:

First Header	Second Header
Content Cell	Content Cell
Content Cell	Content Cell

Here’s an example of an image, which is included using Markdown:

Highlighting for code in Jekyll is done using Base16 or Rouge. This theme makes use of Rouge by default.

// count to ten
for (var i = 1; i <= 10; i++) {
    console.log(i);
}

// count to twenty
var j = 0;
while (j < 20) {
    j++;
    console.log(j);
}

Type on Strap uses KaTeX to display maths. Equations such as \(S_n = a \times \frac{1-r^n}{1-r}\) can be displayed inline.

Alternatively, they can be shown on a new line:

\[f(x) = \int \frac{2x^2+4x+6}{x-2}\]
