Change title size and style in Quarto html

Question

I have a quarto file with an HTML rendering, and I want to change the size and style of the title, how should I proceed? Minimal example:

---
title: "Cars"
format: 
  html

Answer 1

You can use css directly in your code, with font-size to change the size of the title, and font-style to change the style:

---
title: "Cars"
format: 
  html
---

```{css, echo=FALSE}
.title {
  font-size: 100px;
  font-style: italic;
}
```

## MTCars
```{r}
head(mtcars)
```
