marquee pushes content when it gets too long - php

Question

i got a "news" thing on my navigation bar, it uses marquee to have moving text but when the text gets too long, it pushes my content (not the content of the navigation bar but the main content on the website). it is also unable to start from the beginning of the navigation bar and rather chose to start from the middle but really depends on how long the text is...
navigationbar.php
<?php
function echoSelectedClassIfRequestMatches($requestUri)
{
$current_file_name = basename($_SERVER['REQUEST_URI']);
if ($current_file_name == $requestUri)
echo 'class="selected"';
}
?>

Answer 1

Do not use the <marquee> element, it is deprecated.
“This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.”
https://developer.mozilla.org/en/docs/Web/HTML/Element/marquee
But to fix your problem you could try adding overflow: hidden to either .marquee-wrapper or .marquee-wrapper marquee
