Style blogspot blogger date header

To change your blog's date header color and font style, you can do it with a very simple CSS adjustment that will make the date header to float on the left side of your post and to be partially out of the structure like a banner with a colorful appearance.
See the result in the image below:


How to do it

Step 1. Login into your Blogger Dashboard, select Template option > click on Edit HTML 


Step 2. Select Expand Blogger Template and search (CTRL + F) for the following code:

date.header

Or...

.date-header

Step 3. Add the following code snippet just below of it

background:white;
border-bottom: 1px solid #000000;
font-size:12px;
margin-left:-105px;
padding:3px 3px 3px 3px;
width:90px;
word-wrap:break-word;
float:left;
}

Putting it all together, it should look something like this:

.date-header span {
background:#FFD465;
border-bottom: 2px solid #cc0000;
color:#000000;
font-size:12px;
margin-left:-105px;
padding:3px 3px 3px 3px;
width:90px;
word-wrap:break-word;
float:left;}

To modify the style, replace the above bold/colored codes...

to change the background color:

• #FFD465: replace with the hex code of the color you want

to change the border style:

• delete -bottom if you want border all around
• change: 2px to a higher or lower value
• change: solid with dotted if you want a dotted line
• change:  #cc0000 with the hex code of border color

to change the font size and date color:

• for a bigger text, change: 12px to a higher value
• color: replace the hex code (#000000) with the hex of date color

Example:

color: #0000cc;

to change margin-left:
(represents the distance between date and blogger post)

• replace -105px with a bigger/smaller value

float:

• change left to right
