Make a “Really Empty” Blank Page with HTML

1. Code Blogger theme blank blogger blank page

<?xml version="1.0" encoding="UTF-8" ?>
<html xmlns='http://www.w3.org/1999/xhtml' xmlns:b='http://www.google.com/2005/gml/b' xmlns:data='http://www.google.com/2005/gml/data' xmlns:expr='http://www.google.com/2005/gml/expr'>

—– css Yours here —– Enter your css here.

Explain basic code

This code is The most basic structure of the Blogger theme together with:

  • Blogger HTML + namespace layout
  • Meta for mobile/desktop
  • Retrieving blog data such as page names
  • Area for inserting CSS
  • One section for inserting widgets
  • Add credit below

Simple and easy to use for creating minimal Blogger templates.

✔ This section is for declaring XML and defining namespaces.

<?xml version="1.0" encoding="UTF-8" ?>
<html xmlns='http://www.w3.org/1999/xhtml'
      xmlns:b='http://www.google.com/2005/gml/b'
      xmlns:data='http://www.google.com/2005/gml/data'
      xmlns:expr='http://www.google.com/2005/gml/expr'>
  • xmlns:b = Used for Blogger tags such as: <b:if>, <b:section>
  • xmlns:data = Used to extract data from blogs such as data:blog.pageTitle
  • xmlns:expr = Used to process various expressions.

✔ Set Internet Explorer to display like IE7

<head>
  <meta content='IE=EmulateIE7' http-equiv='X-UA-Compatible'/>

✔ Set split screen size for mobile / desktop

<b:if cond='data:blog.isMobile'>
   <meta content='width=device-width,initial-scale=1.0,minimum-scale=1.0,maximum-scale=1.0' name='viewport'/>
<b:else/>
   <meta content='width=1100' name='viewport'/>
</b:if>
  • If it's a mobile phone → use a responsive viewport.
  • If it is a desktop → set the width to 1100px.

✔ Tell Blogger to include content <head> Blogger Standards

<b:include data='blog' name='all-head-content'/>
  • Such as automatic scripts, various meta tags

✔ Name the web page from the blog page name.

<title><data:blog.pageTitle/></title>
  • Use the data that Blogger automatically generates for you.

✔ Section for inserting theme CSS

<b:skin>
   <![CDATA[/* 
    ----- css Yours here -----
   ]]>
</b:skin>
  • <![CDATA[ ]]> = Used to insert code that cannot be directly processed by XML, such as CSS.

✔ Blogger's main content display section

</head>
<body>
  <b:section class='main' id='main' showaddelement='yes'/>
  • <b:section> This is the section where we can add widgets.
  • showaddelement='yes' = Allows you to add gadgets to the layout.

✔ Close HTML structure

</body>
</html>

Sidebar Gadgets/Widgets In Blogger theme we need to add <b:section> Keep in <body> Beside main (Post display section)

✅ 3.1. XML declaration and namespace section

<?xml version="1.0" encoding="UTF-8" ?>
<html xmlns='http://www.w3.org/1999/xhtml' 
      xmlns:b='http://www.google.com/2005/gml/b' 
      xmlns:data='http://www.google.com/2005/gml/data' 
      xmlns:expr='http://www.google.com/2005/gml/expr'>
explain
  • <?xml ...?> → It says it is an XML file that Blogger uses to convert to HTML.
  • xmlns:b → Used for Blogger tags such as: <b:section>, <b:widget>
  • xmlns:data → Used to extract data such as <data:blog.title/>
  • xmlns:expr → Use to insert expressions such as expr:href='data:blog.url'

✅ 3.2. <head> Website header

3.2.1 Supports older Internet Explorer
<meta content='IE=EmulateIE7' http-equiv='X-UA-Compatible'/>
3.2.2 Mobile/Desktop Viewport
<b:if cond='data:blog.isMobile'>
  <meta content='width=device-width,initial-scale=1.0,...' name='viewport'/>
<b:else/>
  <meta content='width=device-width, initial-scale=1.0' name='viewport'/>
</b:if>

How does it work?

  • If you access the website on your mobile phone → use the mobile friendly viewport.
  • If it is a desktop → use full screen.
3.2.3 Auto-load Blogger header
<b:include data='blog' name='all-head-content'/>

together with:

  • Article meta
  • Open Graph
  • Basic Schema
  • Feed
    Very important, do not delete.
3.2.4 Pull the page name as <title>
<title><data:blog.pageTitle/></title>
3.2.5 Load Google Fonts
<link href="https://fonts.googleapis.com/css2?family=Kanit..." />

🎨3.3 All CSS (inside <b:skin>)

Blogger must include CSS inside. <b:skin> only

🧱 4. Website Header

<header>
  <h1><data:blog.title/></h1>
  <nav>
    <ul>
      <li><a expr:href='data:blog.homepageUrl'>Home</a></li>
      <li><a href='#'>About</a></li>
      <li><a href='#'>Contact</a></li>
    </ul>
  </nav>
</header>
explain
  • <data:blog.title/> → Blog name
  • Menu arranged from left to right
  • CSS Sticky Header

📰 5. Content Container Layout

<div class="container">
  <main>
    <b:section id='main'>
      <b:widget type='Blog'/>
    </b:section>
  </main>

  <aside class="sidebar">
    <h3>Gadgets</h3>
    <b:section id='sidebar'/>
  </aside>
</div>

  • Add credit
  • The background color is black.

⬆️ 7. Back-to-Top Button

<button id="back-to-top" class="back-to-top">↑</button>

Usually, there must be some JS as well, such as:


window.addEventListener('scroll', () => {
  document.getElementById('back-to-top').style.display =
    window.scrollY > 300 ? 'block' : 'none';
});


document.getElementById('back-to-top').onclick = () =>

  • Main content flexible
  • Post card design
  • Footer

🔶 4.1. XML declaration and namespace section

<?xml version="1.0" encoding="UTF-8" ?>
<html xmlns='http://www.w3.org/1999/xhtml'
      xmlns:b='http://www.google.com/2005/gml/b'
      xmlns:data='http://www.google.com/2005/gml/data'
      xmlns:expr='http://www.google.com/2005/gml/expr'>

✔ Explain

This is The main structure that bloggers must use:

namespaceduty
b:Use Blogger's system tags such as: <b:section>, <b:widget>
data:Pull data such as <data:blog.title/>
expr:Writing expressions such as: expr:href="data:blog.homepageUrl"

🔶 4.2. <head> — Web header

✔4.2.1 Viewport for mobile
<b:if cond='data:blog.isMobile'>
  <meta content="width=device-width, initial-scale=1.0" />
<b:else/>
  <meta content="width=device-width, initial-scale=1.0" />
</b:if>
✔ 4.2.2 Add Blogger's auto-generated meta and scripts
<b:include data='blog' name='all-head-content'/>

Blogger will automatically add the following:

  • Title / Description of the page
  • OpenGraph
  • Article Schema
  • Canonical URL
  • Feed
  • CSS widget

It is an important part, do not delete it.

✔ 4.2.3 Page Title
<title><data:blog.pageTitle/></title>

Pull names by page, such as:

  • Home → Blog Name
  • Post display page → Post name
  • Page with label → Label name
✔ 4.2.4 Download Google Fonts
<link href="https://fonts.googleapis.com/css2?family=Kanit..." />

Set the font across the site

🔶 4.3. <b:skin> — CSS section of the template

Blogger must include all CSS inside <b:skin><![CDATA[ ... ]]></b:skin>

✔ 4.3.1 Define the main style of the website.
body {
  font-family:'Kanit';
  background:#f7f9fc;
  color:#333;
}

Set background color, font, text color

✔ 4.3.2 Header Sticky
header {
  position:sticky;
  top:0;
  background:#fff;
  box-shadow:0 2px 8px rgba(0,0,0,0.05);
}

When scrolling → Header is attached to the top

✔ 4.3.3 Navigation Menu
nav ul {
  display:flex;
  gap:20px;
  list-style:none;
}

Horizontal menu with Flexbox

✔ 4.3.4 2-column layout structure
.container {
  display:grid;
  grid-template-columns: 300px 1fr;
  gap:20px;
}
columnWidth
SidebarFixed 300px
Main content1fr (fully stretchable)
✔ 4.3.5 Post Card (for article list)
.post-card {
  background:#fff;
  border-radius:12px;
  padding:20px;
  box-shadow:0 4px 12px rgba(0,0,0,0.05);
}

Create beautiful postcards

✔ 4.3.6 Sidebar Box
.sidebar {
  background:#fff;
  border-radius:12px;
  padding:20px;
}

Sidebar has a card-like style.

✔ 4.3.7 Footer
footer {
  background:#222;
  color:#eee;
  text-align:center;
}
✔ 4.3.8 Back-to-top button
.back-to-top {
  position:fixed;
  bottom:20px;
  right:20px;
  background:#008f7a;
  width:50px;
  height:50px;
  border-radius:50%;
  display:none;
}

Hide the buttons for now.

✔4.3.9 Responsive Mobile
@media (max-width:900px) {
  .container {
    grid-template-columns:1fr;
  }
}

Mobile → Change to 1 column

🔶 4.4 parts <body>

✔ Header
<header>
  <h1><data:blog.title/></h1>
  <nav>
    <ul>
      <li><a expr:href='data:blog.homepageUrl'>Home</a></li>

Pull the blog name to display

✔ Layout: Sidebar + Main

📌 Sidebar
<aside class="sidebar">
  <b:section id='sidebar'/>
</aside>

is Widget Placement Area such as:

  • Popular post
  • Label
  • HTML/JS
  • Profile

Users added via Blogger's Layout page

📌 Main Content
<main>
  <b:section id='main'>
    <b:widget type='Blog'/>
  </b:section>
</main>

This is the heart of the template.
Display:

✔ Footer
<footer>
  © <data:blog.title/>
</footer>
✔ Back-to-top Button + Script

<button id="back-to-top" class="back-to-top">↑</button>
Working Script
window.addEventListener('scroll', () => {
  btn.style.display = window.scrollY > 200 ? 'flex' : 'none';
});
