How to Add Alert Blocks to Your Blogger Website

 Enhancing your Blogger website with alert blocks is a great way to capture your readers' attention with important updates, notifications, or announcements. Alert blocks can help emphasize crucial information, making sure it doesn't get lost in your content. In this guide, we’ll walk you through the process of adding alert blocks to your Blogger website easily.

Understanding Alert Blocks

Alert blocks are distinct sections in your blog post that highlight specific information, such as warnings, tips, or important updates. They are usually styled with different colors and icons to stand out from the rest of the content. Here’s why you might want to use them:

• Grab Attention: Make sure your readers don’t miss crucial information.
• Enhance Readability: Break up long texts and emphasize key points.
• Improve Engagement: Keep your readers informed and engaged with essential updates.

Preparing Your Content

Before adding alert blocks, identify the content that needs to be highlighted. This can include:

• Important announcements
• Key points or summaries
• Warnings or cautionary advice
• Special offers or calls to action

Adding HTML and CSS for Alert Blocks

To add alert blocks to your Blogger posts, you need to insert some custom HTML and CSS. Here’s a simple way to do it:

Step 1: Access Your Blogger Theme

1. Log in to your Blogger account.
2. Go to the "Theme" section from the left sidebar.
3. Click on the "Customize" button.
4. Select "Edit HTML" from the options.

Step 2: Insert CSS for Alert Blocks

Add the following CSS code to your theme’s HTML to style the alert blocks:

/* Alert Box by SiteGuide */ .alert { --clr: var(--linkC); --szsp: 20px; position: relative; border-radius: 8px; margin: var(--szsp) 0; padding: calc(var(--szsp) * .6) var(--szsp); font-size: calc(var(--szsp) * .75); line-height: calc(var(--szsp) * 1.3); overflow: hidden; z-index: 1 } .alert:not(.outline) { color: var(--clr) } .alert:not(.outline)::before { content: ""; position: absolute; left: 0; top: 0; width: 100%; height: 100%; background: var(--clr); z-index: -1; opacity: .1 } .alert.outline { border: 1px solid var(--clr) } .alert.info::after, .alert.warning::after, .alert.success::after, .alert.error::after { content: ""; position: absolute; height: calc(100% - var(--sptp)); left: calc(var(--szsp) * 1.125); border-left: 1px solid var(--clr); top: calc(var(--szsp) * 2.4); --sptp: calc(var(--szsp) * 3.2) } .alert.info, .alert.warning, .alert.success, .alert.error { background-repeat: no-repeat; background-size: var(--szsp); background-position: calc(var(--szsp) * .7) calc(var(--szsp) * .7); /* Alert Box by SiteGuide */ padding-left: calc(var(--szsp) * 2.5) } .alert.info { background-image: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 512 512'%3E%3Cpath d='M256 512c141.4 0 256-114.6 256-256S397.4 0 256 0S0 114.6 0 256S114.6 512 256 512zM216 336h24V272H216c-13.3 0-24-10.7-24-24s10.7-24 24-24h48c13.3 0 24 10.7 24 24v88h8c13.3 0 24 10.7 24 24s-10.7 24-24 24H216c-13.3 0-24-10.7-24-24s10.7-24 24-24zm40-144c-17.7 0-32-14.3-32-32s14.3-32 32-32s32 14.3 32 32s-14.3 32-32 32z' fill='%2300a7e6'/%3E%3C/svg%3E") } .alert.warning { background-image: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 512 512'%3E%3Cpath d='M256 512c141.4 0 256-114.6 256-256S397.4 0 256 0S0 114.6 0 256S114.6 512 256 512zm0-384c13.3 0 24 10.7 24 24V264c0 13.3-10.7 24-24 24s-24-10.7-24-24V152c0-13.3 10.7-24 24-24zm32 224c0 17.7-14.3 32-32 32s-32-14.3-32-32s14.3-32 32-32s32 14.3 32 32z' fill='%23ecb621'/%3E%3C/svg%3E") } .alert.success { background-image: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 512 512'%3E%3Cpath d='M256 512c141.4 0 256-114.6 256-256S397.4 0 256 0S0 114.6 0 256S114.6 512 256 512zM369 209L241 337c-9.4 9.4-24.6 9.4-33.9 0l-64-64c-9.4-9.4-9.4-24.6 0-33.9s24.6-9.4 33.9 0l47 47L335 175c9.4-9.4 24.6-9.4 33.9 0s9.4 24.6 0 33.9z' fill='%2341ba79'/%3E%3C/svg%3E") } .alert.error { background-image: url("data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 512 512'%3E%3Cpath d='M256 0c53 0 96 43 96 96v3.6c0 15.7-12.7 28.4-28.4 28.4H188.4c-15.7 0-28.4-12.7-28.4-28.4V96c0-53 43-96 96-96zM41.4 105.4c12.5-12.5 32.8-12.5 45.3 0l64 64c.7 .7 1.3 1.4 1.9 2.1c14.2-7.3 30.4-11.4 47.5-11.4H312c17.1 0 33.2 4.1 47.5 11.4c.6-.7 1.2-1.4 1.9-2.1l64-64c12.5-12.5 32.8-12.5 45.3 0s12.5 32.8 0 45.3l-64 64c-.7 .7-1.4 1.3-2.1 1.9c6.2 12 10.1 25.3 11.1 39.5H480c17.7 0 32 14.3 32 32s-14.3 32-32 32H416c0 24.6-5.5 47.8-15.4 68.6c2.2 1.3 4.2 2.9 6 4.8l64 64c12.5 12.5 12.5 32.8 0 45.3s-32.8 12.5-45.3 0l-63.1-63.1c-24.5 21.8-55.8 36.2-90.3 39.6V240c0-8.8-7.2-16-16-16s-16 7.2-16 16V479.2c-34.5-3.4-65.8-17.8-90.3-39.6L86.6 502.6c-12.5 12.5-32.8 12.5-45.3 0s-12.5-32.8 0-45.3l64-64c1.9-1.9 3.9-3.4 6-4.8C101.5 367.8 96 344.6 96 320H32c-17.7 0-32-14.3-32-32s14.3-32 32-32H96.3c1.1-14.1 5-27.5 11.1-39.5c-.7-.6-1.4-1.2-2.1-1.9l-64-64c-12.5-12.5-12.5-32.8 0-45.3z' fill='%23ff6372'/%3E%3C/svg%3E") } .alert.info { --clr: #3e69a8 } .alert.warning { --clr: #8f6919 } /* Alert Box by SiteGuide */ .alert.success { --clr: #127a5b } .alert.error { --clr: #be2e3c } .alert>strong:first-child, .alert>i:first-child, .alert>b:first-child { display: block; margin-bottom: 8px; font-family: var(--fontC); font-weight: 700; color: var(--clr) } .drK .alert.info { --clr: #00a7e6 } .drK .alert.warning { --clr: #ecb621 } .drK .alert.success { --clr: #41ba79 } .drK .alert.error { --clr: #ff6372 } .alert > ol, .alert > ul { padding-inline-start: 20px; }

This CSS will create three types of alert blocks: info, warning, success, and error, each with a distinct color scheme.

Step 3: Use HTML to Add Alert Blocks in Posts

Now, you can add alert blocks to your blog posts using HTML. Here’s how:

1. Go to the "Posts" section and select the post where you want to add an alert block.
2. Switch to the HTML view in the post editor.
3. Insert the following HTML code where you want the alert block to appear:

HTML Code for default note blocks

<!-- alert default -->
  <div class="alert"><b>Default</b>
    A simple default alert - Lorem ipsum dolor sit amet.
  </div>
  
  <!-- alert outline -->
  <div class="alert outline"><b>Outline</b>
    A simple outline alert - Lorem ipsum dolor sit amet.
  </div>

HTML Code for solid note blocks

<!-- alert variant with solid background -->
  <div class="alert info"><b>Info!</b>
    A simple info alert - Lorem ipsum dolor sit amet.
  </div>
  
  <div class="alert warning"><b>Warning!</b>
    A simple warning alert - Lorem ipsum dolor sit amet.
  </div>
  
  <div class="alert success"><b>Success!</b>
    A simple success alert - Lorem ipsum dolor sit amet.
  </div>
  
  <div class="alert error"><b>Error!</b>
    A simple error alert - Lorem ipsum dolor sit amet.
  </div>

HTML Code for outlined note blocks

<!-- alert variant with outline -->
  <div class="alert info outline"><b>Info!</b>
    A simple info alert - Lorem ipsum dolor sit amet.
  </div>
  
  <div class="alert warning outline"><b>Warning!</b>
    A simple warning alert - Lorem ipsum dolor sit amet.
  </div>
  
  <div class="alert success outline"><b>Success!</b>
    A simple success alert - Lorem ipsum dolor sit amet.
  </div>
  
  <div class="alert error outline"><b>Error!</b>
    A simple error alert - Lorem ipsum dolor sit amet.
  </div>

Replace the placeholder text with your actual content. You can customize the messages inside the <strong> tags and the body of the alert blocks.
