solve CSS errors in Blogger template using Firebug

Knowing CSS can help you in solving Blogger template errors ,or make some customization . But how to do that ? how to find where is the trouble or find what CSS attribute you need to change when  make customization ? In this post ,I will show you what I did : using Firebug (a Firefox add-on ) to work with CSS .
Firebug is a great add-on of Firefox browser ,it's very popular in web development because it can help us inspecting website elements ,debugging errors in CSS ,script ,seeing web layout ....
To use Firebug ,first ,Firefox browser must be installed in your PC . Then go to website : http://getfirebug.com/ ,click on Install Firebug to get the latest version and installed this add-on to Firefox .


After installing Firebug ,you will see an new button in browser window ,this button has the image of a bug .

Enter the Blogger blog you want to fix errors or make customization
When the page fully loaded ,click on firebug button ,the firebug window will appear at the bottom of browser window .

Click on the arrow button in firebug window
 
After click this button ,there will be a rectangle around the element that the mouse is pointing .  Move your mouse pointer to the element you want to change size or fix error
In the right panel of firebug window ,you will see the CSS tags of element which you are pointing .


You can click on the value of these CSS attributes to change value of them ,for example ,in this picture ,I changed width of an element in the right panel ,and see how it look after changing immediately in browser window .
You can also add more attributes to a CSS tags to make it display as you want ,for example ,you want color of all text in an element changed to white color,just right click on right-panel and ,choose new property ,and then add color:#fff;

That's very easy and fun because you can see how your site is right after making changes .

But how to know which CSS need to change ,or meaning of CSS tags or what need to add to make it display as you want ? You can see it easily in my previous post : 31 online CSS cheatsheets that may helpful .

You can use Firebug to see the element layout ,the right or left margin ,padding... in Layout tab in right panel .
When you finish the work ,just go to Blogger template (xml file) ,and add the tags or attributes that you've just added in Firebugs to your template .
There're many functions that Firebug can help you in finding bugs and fixing errors .It's very easy to use ,believe me ,just need a little of time ,you can handle this software and make it work for you ^^
