徽标（浮动：左侧）和列表（浮动：右侧）不可见
[英]Logo (float: left) & list (float: right) is not visible
问题描述
在HTML5和CSS3中，徽标需要浮动到左上角，项目/菜单列表需要浮动到右上角。
在此处的输出中，由于某种原因徽标不可见。 但是提到了“ alt”，“代替了徽标”。
这是我身边收到的输出。 我在网页顶部用白色标记了它：
/*---------------------------------------------------------*/ /*Basic Setup*/ /*---------------------------------------------------------*/ * { margin: 0; padding: 0; box-sizing: border-box; } html { background-color: #fff; color: #555555; font-family: 'Lato', 'Arial', sans-serif; color: #555555; font-size: 20px; font-weight: 300; text-rendering: optimizeLegibility; } /*---------------------------------------------------------*/ /*----------------REUSABLE COMPONENTS----------------------*/ /*---------------------------------------------------------*/ .row { max-width: 110px; margin: 0 auto; } /*-------------------------HEADINGS------------------------*/ h1 { margin: 0; margin-bottom: 20px; color: #fff; font-size: 240%; font-weight: 300; text-transform: uppercase; letter-spacing: 1px; word-spacing: 4px; } /*-----------------BUTTONS---------------*/ .btn:link, .btn:visited { display: inline-block; color: #fff; padding: 10px 30px; font-weight: 300; text-decoration: none; border-radius: 200px; transition: background-color 0.2s, border 0.2s, color 0.2s; } .btn-full:link, .btn-full:visited { background-color: #e67e22; border: 1px solid #e67e22; color: #fff; margin-right: 15px; } .btn-ghost:link, .btn-ghost:visited { color: #e67e22; border: 1px solid #e67e22; } .btn:hover, .btn:active { background-color: #cf6d17; } .btn-full:hover, .btn-full:active { border: 1px solid #cf6d17; } .btn-ghost:hover, .btn-ghost:active { color: #fff; border: 1px solid #cf6d17; } /*------------------------------------------------------------------------*/ /*----------------------------HEADER--------------------------------------*/ /*------------------------------------------------------------------------*/ header { background-image: linear-gradient(rgba(0, 0, 0, 0.7), rgba(0, 0, 0, 0.7)), url(Images/hero.jpg); background-size: cover; background-position: center; height: 100vh; } .hero-text-box { position: absolute; width: 1140px; top: 50%; left: 50%; transform: translate(-40%,-50%); } .logo { height: 100px; width: auto; float: left; margin-top: 20px; } .main-nav { float: right; list-style: none; margin: 55px; } .main-nav li { display: inline-block; margin-left: 40px; } .main-nav li a:link, .main-nav li a:visited { padding: 8px 0; color: #fff; text-decoration: none; text-transform: uppercase; font-size: 90%; border-bottom: 2px solid transparent; transition: border-bottom 0.2s; } .main-nav li a:hover, .main-nav li a:active { border-bottom: 2px solid #e67e22; }

您的元素正确浮动，但是，父级的最大宽度为类row提供的110px，因此，基本上，它们没有太大的放置空间
浮动徽标在左侧，内容在右侧
