Two DIVs on the same place

Question

My "search box and social icons" are hidden behind my main-menu. This is probably because of my .hide-menu class. I have a jQuery plugin that makes the main-menu appear when scrolling-up and makes it disappear when scrolling-down. What I want to achieve is that the "search box and social icons" DIV show always and below the main-menu. Is this possible?

Answer 1

Easiest is probably to use sibling selector between .site_header and #search-social. Make sure that #search-social is positioned. Something like:

#search-social {
  margin-bottom: 20px;
  position: relative;
}

header.site_header ~ #search-social {
  top: 40px;
}
header.site_header.hide-menu ~ #search-social {
  top: 0px;
}

Example (with a testbutton): https://jsfiddle.net/7f6q75h8/2/

Note: Top styling needs some adjustment depending on the menu height.

Answer 2

I don't know if this is what you want but may lead you in right direction. just added a jquery function to determine the state when menu bar is visible,

function adjustMenu() {
   if (!$('#nav').hasClass('hide-menu')) {
      $('#search-social').css('margin-top', $('#nav').height() + 'px');
   } else {
      $('#search-social').css('margin-top', '0px');
   }
}

this function is called on page load as well as inside the onscroll event of page

$(window).scroll(function() {
   adjustMenu();
});

here is the updated fiddle

there are better ways if you can edit in the plugin code you are using.

Answer 3

Maybe you can use position:absolute;

Else you can add a class on the wrapper when you wanna show or hide something.

.wrapper .active .div2{
   display:block;
}
