About this app

내 웹 프로젝트를 iPhone과 iPad에서 엽니다. HTML Web Preview는 HTML과 연결 파일이 들어 있는 폴더를 열고, 웹 화면과 JSON·소스를 함께 확인하는 앱입니다. 직접 만든 학습 자료, 웹 문서, 간단한 도구와 시제품을 기기에서 확인할 수 있습니다. • 폴더 하나로 연결 파일까지: HTML, CSS, JavaScript, 이미지와 JSON을 폴더 구조 그대로 엽니다. • 원본은 그대로: 앱은 선택한 파일과 폴더를 수정하지 않습니다. JSON 정리 보기와 원문을 전환하고, 다른 앱에서 수정한 내용은 새로고침으로 읽을 수 있습니다. • 먼저 확인하고 실행: JavaScript를 끈 미리보기로 시작합니다. 내용을 확인한 뒤 신뢰할 수 있는 프로젝트만 실행해야 합니다. 일부 웹 기능에는 별도 확인을 거치는 호환 모드가 필요합니다. • 화면에 맞춰 보기: 조작 버튼을 접거나 모바일·태블릿·컴퓨터 화면 비율로 표시 영역을 바꿉니다. 화면 비율 선택은 실제 기기의 모든 환경을 재현하지 않습니다. • 오류 확인: 파일 누락과 페이지 오류를 구분하고 프로젝트 실행 기록을 확인합니다. 사…

What you can learn from HTML Web Preview: JS CSS JSON

Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 12 screenshots above are HTML Web Preview: JS CSS JSON's answers to those questions — they're public, they're real, and they made it through Apple's review.

What the numbers say: HTML Web Preview: JS CSS JSON runs a light set with one background colour (#FCFCFC) carried across every screenshot — the listing reads as a single poster when the shots sit side by side in search results. The accent colour we picked up, #1C5CCC, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.

Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
