我正在做一個項目,我需要創建的div上升,其中用戶可以改變他的照片,所以,我這樣做:股利不觸及瀏覽器甚至CSS的頂端重置

<div class="mudar_foto_form" style="z-index: 5; position: fixed; width: 100%; height: 100%; background-color: rgba(0, 0, 0, 0.5);"> 
</div> 

但是,在div沒有到達頁面的頂部: http://prntscr.com/eys8lp

我甚至嘗試使用:

html, body { 
     margin: 0px; 
     padding: 0px; 
     border: 0px; 
    } 

即使這樣一個CSS復位:

@charset "utf-8"; 
/* CSS Document */ 
html, body, div, span, applet, object, iframe, 
h1, h2, h3, h4, h5, h6, p, blockquote, pre, 
a, abbr, acronym, address, big, cite, code, 
del, dfn, em, img, ins, kbd, q, s, samp, 
small, strike, strong, sub, sup, tt, var, 
b, u, i, center, 
dl, dt, dd, ol, ul, li, 
fieldset, form, label, legend, 
table, caption, tbody, tfoot, thead, tr, th, td, 
article, aside, canvas, details, embed, 
figure, figcaption, footer, header, hgroup, 
menu, nav, output, ruby, section, summary, 
time, mark, audio, video { 
    margin: 0; 
    padding: 0; 
    border: 0; 
    font-size: 100%; 
    font: inherit; 
    vertical-align: baseline; 
} 
/* HTML5 display-role reset for older browsers */ 
article, aside, details, figcaption, figure, 
footer, header, hgroup, menu, nav, section { 
    display: block; 
} 
body { 
    line-height: 1; 
} 
ol, ul { 
    list-style: none; 
} 
blockquote, q { 
    quotes: none; 
} 
blockquote:before, blockquote:after, 
q:before, q:after { 
    content: ''; 
    content: none; 
} 
table { 
    border-collapse: collapse; 
    border-spacing: 0; 
} 

但仍然沒有觸及頁面的頂部,有什麼建議嗎?

你能在的jsfiddle或類似上傳你的代碼?設置'top:0; left:0; width:100%; height:100%'應該可以解決你的問題,但是很高興看到你當前的代碼工作到目前爲止。 –

嗯......'top:0;'? – aahhaa

嘗試添加'left:0; top:0' - 你沒有給你的元素一個位置,所以瀏覽器必須猜測你的意思。 –

所以,我忘了做頂:0,這要歸功於Niet的黑暗ABSOL和wlin
