배경화면 질문드립니다

http://tkwlsrhror.dothome.co.kr 보시면 배경화면이 한줄씩 나와서 전체배경 느낌이 안드는데

html {overflow-y:scroll}

body {box-sizing:border-box; width:97%; padding:0;font-size:0.75em;font-family:dotum; background:url('http://tkwlsrhror.dothome.co.kr/img/qorud.png');}

html, h1, h2, h3, h4, h5, h6, form, fieldset, img {margin:0;padding:0;border:0}

h1, h2, h3, h4, h5, h6 {font-size:1em;font-family:dotum}

article, aside, details, figcaption, figure, footer, header, hgroup, menu, nav, section {display:block}
