Style blogspot blogger date header

This can be a really cool addition to your blog which can be easily customized to suit your layout and design. What we are going to do in this tutorial is to change the Blogger date header background color with some simple CSS adjustments that will make the date header float on the left side of your post and be partially out of the structure, like a banner with a colorful appearance.

Customize the Date Header of a Blogger Blog

Step 1. Log in your Blogger account and go to Template > Edit HTML

Step 2.Click anywhere inside the code area and search (CTRL + F) for the following code:

.date-header span

Below this code you should see some lines like these:

.date-header span {
  background-color: $(date.header.background.color);
  color: $(date.header.color);
  padding: $(date.header.padding);
  letter-spacing: $(date.header.letterspacing);
  margin: $(date.header.margin);
}

Step 3. You will need to replace the code above with this one:

.date-header {
margin: 0px 0px -50px -190px;
}
.date-header span {
background-color: #DDEDAA;
color: #444;
padding: 16px;
border-radius: 70%;
border: 3px solid #bada55;
}
.date-header:before {
background: none repeat scroll 0 0 #FCFCFC;
border: 10px solid #FFBD54;
border-radius: 100%;
bottom: -50px;
content: "";
display: block;
height: 30px;
position: absolute;
width: 30px;
z-index: 10;
margin-left: 140px;
}
.date-header:after {
background: none repeat scroll 0 0 #F9F9F9;
border: 7px solid #bada55;
border-radius: 100%;
bottom: -17px;
content: "";
display: block;
height: 15px;
position: absolute;
width: 15px;
z-index: 10;
margin-left: 166px;
}

Step 4. Click the "Save template" button to save the changes. That's it!
