从joomla网站删除编辑选项

I am new in joomla and i am developing one website in joomla. I am using the articles for some pages. Now i have seen that in my website in all most place there is one option is there for modification content from website. How can i hide or remove that edit option?

Please see below image for that option.

This edit option is actually module editing.

You can disable it from Joomla global configuration. There is a setting Mouse-over edit icons in set it to None to remove this.

This is by default, only available to the admins of the site, so I wouldn't be too worried about it. Alternatively the easiest is to go to System Global Configuration > Mouse-over edit icons and set to none.
