This time Droidnur will provide a simple tutorial on How to Create a 404 Error Page on Blogger. In this tutorial, we will use the Error Page Conditional Tag to create it, because by using the Conditional Tag the work of this tutorial will be easier, and the Error page can load quickly as it should because it does not use Redirect.
Step to Creating a 404 Error Page on Blogger
Here's a simple way to Create a 404 Error Page, first we wrap the page that won't appear on the 404 Error page/page except on the Error page, here's the concept:
<body>
<b:if cond='!data:view.isError'> … </b:if>
... This area contains the main sections in a blog such as the main-wrapper, sidebar-wrapper, to the footer-wrapper. This area will be ignored because we are in a state of denial. ...
</b:if>
<b:if cond='data:view.isError'> … </b:if>
<div id="container-error">
<div id="error-page">
Write something here. This section will only appear when the page is not found.
</div>
</div>
</b:if>
</body>The rest is just adding CSS to beautify 404 Pages

#container-error h3,#container-error h4{display:block;text-align:center;margin-bottom:30px;font-size:2rem;font-weight:700;color:#aaa}
#container-error h3{margin-top:30px}
#error-page{position:relative;max-width:920px;margin:6% auto;line-height:normal}Demo
