-We have defined some CSS rules to limit the height of
-code blocks. Now we can test if these rules work on code
-blocks and text output:
-
-```{r}
-# pretend that we have a lot of code in this chunk
-if (1 + 1 == 2) {
- # of course that is true
- print(mtcars)
- # we just printed a lengthy data set
-}
-```
-
-Next we add rules for a new class `scroll-100` to limit
-the height to 100px, and add the class to the output of
-a code chunk via the chunk option `class.output`:
-
-```{css, echo=FALSE}
-.scroll-100 {
- max-height: 100px;
- overflow-y: auto;
- background-color: inherit;
-}
-```
-
-```{r, class.output="scroll-100"}
-print(mtcars)
