#### HTML

* \<nav> 요소는 해당 코드가 페이지 탐색임을 알리는 역할을 한다.&#x20;
* 접근성을 위해서  언어가 바뀐다면 마크업에 lang 속성을 설정한다.&#x20;

#### JS

* 첫글자만 대문자로 변환하기 예제&#x20;

```javascript
const name = 'hanna'
name[0].toUpperCase() + name.slice(1) // Hanna
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://shhn0509.gitbook.io/hanna/hanna-log/march/3.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
