목차
예시
Form controls are styled with a mix of Sass and CSS variables, allowing them to adapt to color modes and support any customization method.
<div class="mb-3">
<label for="exampleFormControlInput1" class="form-label">Email address</label>
<input type="email" class="form-control" id="exampleFormControlInput1" placeholder="name@example.com">
</div>
<div class="mb-3">
<label for="exampleFormControlTextarea1" class="form-label">Example textarea</label>
<textarea class="form-control" id="exampleFormControlTextarea1" rows="3"></textarea>
</div>크기 조절
.form-control-lg와 .form-control-sm 클래스를 사용해서 크기를 다르게 설정할 수 있습니다.
<input class="form-control form-control-lg" type="text" placeholder=".form-control-lg" aria-label=".form-control-lg example">
<input class="form-control" type="text" placeholder="Default input" aria-label="default input example">
<input class="form-control form-control-sm" type="text" placeholder=".form-control-sm" aria-label=".form-control-sm example">Form text
block-level 또는 inline-level의 폼 텍스트는 .form-text를 사용해서 생성할 수 있습니다.
Form text should be explicitly associated with the form control it relates to using the
aria-describedby attribute. This will ensure that assistive technologies—such as screen readers—will announce this form text when the user focuses or enters the control.
Form text below inputs can be styled with .form-text. If a block-level element will be used, a top margin is added for easy spacing from the inputs above.
Your password must be 8-20 characters long, contain letters and numbers, and must not contain spaces, special characters, or emoji.
<label for="inputPassword5" class="form-label">Password</label>
<input type="password" id="inputPassword5" class="form-control" aria-describedby="passwordHelpBlock">
<div id="passwordHelpBlock" class="form-text">
Your password must be 8-20 characters long, contain letters and numbers, and must not contain spaces, special characters, or emoji.
</div>Inline text can use any typical inline HTML element (be it a <span>, <small>, or something else) with nothing more than the .form-text class.
Must be 8-20 characters long.
<div class="row g-3 align-items-center">
<div class="col-auto">
<label for="inputPassword6" class="col-form-label">Password</label>
</div>
<div class="col-auto">
<input type="password" id="inputPassword6" class="form-control" aria-describedby="passwordHelpInline">
</div>
<div class="col-auto">
<span id="passwordHelpInline" class="form-text">
Must be 8-20 characters long.
</span>
</div>
</div>비활성화
disabled 불리언 속성을 추가하면 비활성화 외형이 되며, 포인터 이벤트가 삭제되면서 포커싱되지 않습니다.
<input class="form-control" type="text" placeholder="Disabled input" aria-label="Disabled input example" disabled>
<input class="form-control" type="text" value="Disabled readonly input" aria-label="Disabled input example" disabled readonly>읽기 전용
readonly 불리언 속성을 추가함으로써 입력 값의 변경을 막을 수 있습니다. disabled와 달리 readonly 입려값은 계속 포커싱 및 선택이 가능합니다.
<input class="form-control" type="text" value="Readonly input here..." aria-label="readonly input example" readonly>읽기 전용 일반 텍스트
폼 내의 <input readonly> 요소를 일반 텍스트로 표시하고 싶은 경우, .form-control-plaintext 클래스를 사용합니다. 기본 폼 필드의 스타일을 삭제하고 그에 맞는 마진과 패딩을 유지한 일반 텍스트로 보여집니다.
<div class="mb-3 row">
<label for="staticEmail" class="col-sm-2 col-form-label">Email</label>
<div class="col-sm-10">
<input type="text" readonly class="form-control-plaintext" id="staticEmail" value="email@example.com">
</div>
</div>
<div class="mb-3 row">
<label for="inputPassword" class="col-sm-2 col-form-label">Password</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="inputPassword">
</div>
</div><form class="row g-3">
<div class="col-auto">
<label for="staticEmail2" class="visually-hidden">Email</label>
<input type="text" readonly class="form-control-plaintext" id="staticEmail2" value="email@example.com">
</div>
<div class="col-auto">
<label for="inputPassword2" class="visually-hidden">Password</label>
<input type="password" class="form-control" id="inputPassword2" placeholder="Password">
</div>
<div class="col-auto">
<button type="submit" class="btn btn-primary mb-3">Confirm identity</button>
</div>
</form>파일 선택
<div class="mb-3">
<label for="formFile" class="form-label">Default file input example</label>
<input class="form-control" type="file" id="formFile">
</div>
<div class="mb-3">
<label for="formFileMultiple" class="form-label">Multiple files input example</label>
<input class="form-control" type="file" id="formFileMultiple" multiple>
</div>
<div class="mb-3">
<label for="formFileDisabled" class="form-label">Disabled file input example</label>
<input class="form-control" type="file" id="formFileDisabled" disabled>
</div>
<div class="mb-3">
<label for="formFileSm" class="form-label">Small file input example</label>
<input class="form-control form-control-sm" id="formFileSm" type="file">
</div>
<div>
<label for="formFileLg" class="form-label">Large file input example</label>
<input class="form-control form-control-lg" id="formFileLg" type="file">
</div>색상
Set the type="color" and add .form-control-color to the <input>. We use the modifier class to set fixed heights and override some inconsistencies between browsers.
<label for="exampleColorInput" class="form-label">Color picker</label>
<input type="color" class="form-control form-control-color" id="exampleColorInput" value="#563d7c" title="Choose your color">데이터 목록
데이터 목록을 사용하면 <input> 안에서 엑세스(및 자동 보완) 할 수 있는 <option> 그룹을 작성할 수 있습니다. 이들은 <select> 요소와 비슷하지만 목록 표시에는 많은 제한과 차이가 있습니다. 대부분의 브라우저나 운영 체계는 <datalist> 요소를 어느 정도 지원하고 있지만, 그 표시에는 일관성이 없습니다.
자세한 내용은 support for datalist elements를 참고해 주세요.
<label for="exampleDataList" class="form-label">Datalist example</label>
<input class="form-control" list="datalistOptions" id="exampleDataList" placeholder="Type to search...">
<datalist id="datalistOptions">
<option value="San Francisco">
<option value="New York">
<option value="Seattle">
<option value="Los Angeles">
<option value="Chicago">
