This exercise was a very straightforward warmup : the flag was split in threeparts (well, two in my case) and put in comments in three different sourcefiles on the site :
### Index
view source on the index page showed the following HTML comment :
```html
```
We can also see that a script and a stylesheet are loaded :
```html<link rel="stylesheet" type="text/css" href="mycss.css"><script type="application/javascript" src="myjs.js"></script>```
### Stylesheet
If we examine the stylesheet, we can see that in ends with a CSS comment :
```css/* I learned CSS! Here's part 2/3 of the flag: ct0r_g4dget_9dd3b33c} */```
### Script
Similarly, the `myjs.js` ends with the following comment :
```javascript/* I learned JavaScript! Here's part 3/3 of the flag:  */```
So if we concatenate the three parts, we get the flag :`picoCTF{ur_4_real_1nspect0r_g4dget_9dd3b33c}`
