You want to use CSS tab of tabs, tab-size attribute may be used; tab-size attribute specifies the width of the tab. Tabs (tab) characters usually show a space character in an HTML document.
In addition to some elements, such as <textarea> and <pre>, the results of tab-size attribute is valid only for this element.
grammar:
tab-size: number|length;Property values:
● number: the number of tabs for each set of space characters (tab) of the characters to be displayed. The default value is 8.
● length: a length setting tab (tab) characters. However, most browsers do not support it.

Firefox supports another alternative attribute of the attribute, i.e. -moz-tab-size attribute; Opera support another alternative attribute of the attribute, i.e. -o-tab-size attribute.
