Thank you very much for this fantastic package!
Using Chrome and your skeleton, there is a bug with the line when adding months.

I tried with Month abbreviations. But sadly the date doesn't render on a single line and it doesn't look good on my own resume.

Would it be possible to fix these issues? Or how can I add months on my resume?
@lgnbhl Glad you like pagedown!
As a hotfix, I can propose you to add the following CSS rules to your Rmd file:
---
title: "Lijia Yu's resume"
author: Lijia Yu
date: "`r Sys.Date()`"
output:
pagedown::html_resume:
# set it to true for a self-contained HTML page but it'll take longer to render
self_contained: false
---
```{css, echo=FALSE}
.date {
--decorator-horizontal-margin: 0.1in;
max-width: var(--date-block-width);
}
.date span {
text-align: center;
}
.date span:nth-child(2)::before {
right: 0;
}
```
Aside
================================================================================
{width=80%}
...
Here's a screenshot I got with these rules.

Since this is a hotfix I've done quickly, I'ld prefer that you take some time to test it.
Tell us if this is OK for you.
It works perfectly. Thank you!
@yihui I wonder whether we should modify resume.css for this.
I think we should.
