[ As you requested madam ] Easy.

Relax zarry. The world is not over! Haha. Firstly, you 'were' having this 'problem' right? Dont say it's blogger fault coz everyone's so going to laugh at you my dear.

This was what you have right.

Click on the 'edit html'.
This are obviously the the html codes.

The ones that I highlighted are the ones you have to edit it yourself. Serious.

Those are actually the 'closing doors' of every paragraph, can be found AFTER the very last word of every paragraph. So, (konon nyer) please identify the last word of the paragraphs from the html then edit!

(Below)

The ones highlighted in yellow is the opening and the closing of the paragraph. The ones underlined in red is just the codes to show that you edited the font's size and colors. As you can see both appeared in all lines.

It's because both are applied in all lines.
