결과물

vh unit stands for viewport height, 

단위 vh -> viewport height , 화면의 100%가 100vh임

 

 

input type이 password일 때 minlength="8" 이렇게 설정할 수 있음.

-> pattern 속성을 이용해서 바꿔보자 (아래 정리)

🔑 pattern 속성을 사용한 비밀번호 유효성 검사

비밀번호 입력 필드에서 type="password"를 사용할 때, pattern 속성을 추가하면 비밀번호가 특정 규칙(정규식)에 맞는지 검사할 수 있다.

<input id="new-password" type="password" pattern="[a-z0-5]{8,}" required />
  • pattern="[a-z0-5]{8,}" → 소문자(a-z) 또는 숫자(0~5)로 이루어진 8글자 이상만 허용
  • -> A-Z 추가하면 대문자도 가능
  • minlength 속성을 삭제 → pattern 속성만으로 최소 길이(8글자 이상)를 지정할 수 있기 때문
  • {8,} → 최소 8글자 이상 입력해야 함

 

Select element

        <label>How did you hear about us?
          <select>
            <option value="">(select one)</option>
            <option value="1">freeCodeCamp News</option>
            <option value="2">freeCodeCamp YouTube Channel</option>
            <option value="3">freeCodeCamp Forum</option>
            <option value="4">Other</option>
          </select>
        </label>

option에 있는 value 값은 서버에 데이터 보낼 때 저렇게 보내짐!

 

CSS selector

input[type="file"] {  /* 이건 속성 selector 인데 type이 file인 input을 가리킨다. */
  padding: 1px 2px;
}

 

fieldset:last-of-type {  /* fieldset 중에서 가장 마지막 거! */
  border-bottom: none;
}

이번 과정은 앞에 과정들 복습하면서 좀더 심화된 내용 같았다. 스타일 부분에서는 하라는 대로 따라 했기 때문에 잘 와닿진 않았지만 html 부분에서 배운 건 많다!
