php - 当内容太长时字幕会推送内容

标签 php html css

我的导航栏上有一个“新闻”的东西，它使用选取框来移动文本，但是当文本太长时，它会推送我的内容(不是导航栏的内容，而是网站上的主要内容) .它也无法从导航栏的开头开始，而是选择从中间开始，但实际上取决于文本的长度...

导航栏.php

<?php
function echoSelectedClassIfRequestMatches($requestUri)
{
    $current_file_name = basename($_SERVER['REQUEST_URI']);

    if ($current_file_name == $requestUri)
        echo 'class="selected"';
}
?>

  • 所有内容之上的包装器

    .content-wrapper { background-image: url("/images/background/content.jpg") !important;宽度:85%；边框:1px 实心#000；背景图像:-webkit-linear-gradient(底部，#1a1b1f，#212528)；背景图像:-moz-linear-gradient(底部，#1a1b1f，#212528)；背景图像:-o-线性渐变(底部，#1a1b1f，#212528)；背景图像:线性渐变(到顶部，#1a1b1f，#212528)；边距:自动；

最佳答案

不要使用 <marquee>元素，它已被弃用。

“此功能已过时。虽然它在某些浏览器中可能仍然有效，但不鼓励使用它，因为它可能随时被删除。尽量避免使用它。”

但要解决您的问题，您可以尝试添加 overflow: hidden到 .marquee-wrapper或 .marquee-wrapper marquee
