The presence of the WordPress admin bar results in extra whitespace on the page, while including

In the process of creating my very first custom WordPress theme, I encountered an issue with whitespace at the top of the body. This was caused by calling wp_head(); in header.php and including the header on each page. To offset this whitespace, I added a 1px padding to the top and bottom of my content div. The drawback is that every page then displayed a scroll bar, regardless of its content length. If not logged in, a 2px scroll bar appears; if logged in, it's 2px plus the height of the wp header.

Despite several attempts to adjust the overflow settings on the body and content divs, I have not been successful in resolving the issue.

One approach I tried was setting the content div with

position: absolute; overflow: auto
. This resolved the issue when logged out, but created a scroll bar when logged into the admin page.

body {
  margin: 0;
  width: 100%;
  background-color: rgb(255, 192, 203); //Color used to highlight any white space.
}
.header {
  width: 15vw;
  height: 100vh;
  padding: 0 1vw;
  position: fixed;
  background-color: rgb(51, 51, 51);
}
.content {
  padding: 1px 0;
  margin-left: 17vw;
  background-color: rgb(20, 20, 20);
  color: white;
  min-height: 100vh;
}
<!--header.php-->
  <body>
    <?php wp_head(); ?>  
    <div class="header"></div>
<!--end header.php-->

<!--page.php-->
    <?php get_header(); ?>
    <div class="content">
      All the page content goes here.
    <div>
    <?php get_footer(); ?>
<!--end page.php-->

<!--footer.php-->
    <?php wp_footer(); ?>
  </body>
<!--end footer.php-->

I am seeking a solution where pages with insufficient content won't display a scroll bar and will hide the wp header whitespace. Any guidance or suggestions on alternative methods would be greatly appreciated.

Answer №1

The extra space you're noticing is a result of the WP admin bar.

There have been numerous discussions on Stack Overflow regarding this issue.

When working on my WP custom themes, I don't rely solely on CSS to fix this. I prefer handling it through functions.php

// disabling the logged in header bar
add_filter( 'show_admin_bar', '__return_false' );

Hopefully implementing this solution will help you too. Just remember to remove any CSS attempts you've made to address the problem.

It seems like the issue may be related to collapsed margins. Even though the .content DIV itself doesn't have any margins, the margins of its child elements like <h1> and <p> can extend beyond the DIV and create extra space above and below. This is why you're seeing the extra whitespace.

You've already found a solution by adding a 1px padding to the content container. To fully resolve the issue, you can also add box-sizing: border-box to the .content DIV. This will include the padding in the overall height calculation, preventing the unwanted scrolling behavior.
