Different browser display web pages in different ways: One more reason why Webmaster should have more than one browser

I have previously explained Advantages of having more than one browser and emphasized with another post What to do when you cannot upload photos, download web pages, sign in, get error messages, etc., (not a "cure all").

Webmasters (professionals who are in charge of a website) especially need many browsers for they should be interested in how the website they are managing is seen by visitors who may be using all kind of web browsers. Bloggers are by default webmasters though their job is made easier as much of what professional webmaster have to do is done by their blogging software/platform. But the necessity of having many web browsers still apply to them.

As an example, I tried to center a Google AdSense site search box in a blog Header. For this, you will need to apply for a Google AdSense account which you can do so via a link in

I use the pair of inline CSS (cascading stylesheet) <span style="text-align:center;"> and </span;"> to surround the script to display the Google AdSense site search box to try to center the search box. But let us look at how the site search box is displayed in different browsers:

Centering Google site search box in Internet Explorer 7.0.5730.131C

Internet Explorer 7

The search box as well as the text that is added below the script in the New Blogger HTML/Javascript Page Element is centered as intended.

Centering Google site search box in FireFox 2.0.0.12

Note that while the text below the site search box is centered, the Google AdSense site search box itself is aligned to the left, and not centered as intended.

Centering Google site search box in Opera 9.26

Note that in Opera web browser, the Google AdSense search box is also not centered while the text is centered.
