How to change width of Posts, Body and Sidebar in Blogger
Normally you can easily do that by using the default
template editor that Blogger provides you, but in most cases it does not
support custom templates so you would need to manually change the HTML code
yourself.
Advantages:
You can place wider widgets on your sidebar - very useful
especially for ads
You can have larger images in your posts
Gives your blog a better look
Changing the width:
Now before you begin doing any changes to your template, it
is highly advisable that you first create a backup just in case you are not
happy with the final results or have accidentally changed the wrong code.
On your right sidebar in the Blogger Administration panel,
head into Template, then on the top right side you should see a button
Backup/Restore. Click on that and then click on the orange button that says
Download full template.
Now that you have made a backup of your template, you can
begin experimenting with the width. Below you will find the three different
codes being used for all three parts of your template. When you have opened up
the HTML editor for your template, simply search for each of these codes.
Overall blog width:
#outer-wrapper {
Sidebar width:
#sidebar-wrapper {
Posts width:
#main-wrapper {
Below each of these codes, you should find another code that
says the following:
width: 500px;
In this case, the 500px is just an example. Yours could be
560px, 400px, etc. Keep in mind, in some cases you may not have px being used
but %. Now you may begin changing that value.
Advice:
Always use the preview feature before saving your template
and when you are sure you changed everything to your taste, you may finally
click on the save button.
