My questions/answers have code blocks and lengthy ones, I would like to have horizontal scroll bars instead of wraping the text. What kind of format I should do to achive this. Please help me.
if you mean code blocks - as displayed with lines starting at four or more spaces - like this:
...then I would recommend to learn how to improve formatting of your code.
If you are posting huge blocks of code - perhaps you are posting too much code. One should only include the portions of the code that he/she feels are relevant to the problem.
( alert! )
In case it was not clear - it's a little bit annoying to have to scroll through text/code like that. Unless it is explicitly required ( love to get some examples if there are some ), then single long lines of text or code should be used sparingly.
