I've seen "Tuts+. PSD to WordPress – Minimal Portfolio Theme" and the author uses the tab completion "sep" and then presses tab and voila he gets multiple line comment separator for CSS something like:
/****************************************************************************/
/* Name Here */
/****************************************************************************/
I want to know how can I achieve this in sublime text? Using what package?
The tab completion you saw was most likely a custom snippet
Go to Tools > New Snippet and add the following code
<snippet>
<content><![CDATA[
/****************************************************************************/
/* ${1:Name Here} */
/****************************************************************************/
]]></content>
<tabTrigger>sep</tabTrigger>
<scope>source.css</scope>
</snippet>
${1:Name Here}
is a variable that will focus your cursor to that point
The <tabTrigger>sep</tabTrigger>
is the defined text that will fire the snippet code with tab
The <scope>source.css</scope>
indicates that the snippet will fire when your syntax is set to CSS.
Save with the .sublime-snippet
file extension. Example: css-sep.sublime-snippet
