How not to get crazy?

We live in XXI century, our lives have become easier thanks to lots of inventions. But have you ever thought about our addiction to technology? It has got to every part of my life and I haven’t even realized that. I wake up thanks to an alarm clock on my mobile phone, during breakfast I check the news on my notebook and all the time I look at my electronic clock to check the time. At university I use PC in laboratories, lecturers show us what they do on their own computers using projectors.

It turns out that it is there, but the declarations are strikethrough. This means you have just encountered some kind of CSS specificity issue. You could just add the !important flag to your declarations and have it done. Is it a good solution? Never. I do not say you should never use !important though. What I really want to say is that you should never use !important if you are not aware of the consequences.
