If you create css.xml with this content then you'll get css highlighting and code-completion:

<?xml version="1.0" encoding="UTF-8"?>
<filetype binary="false" default_extension="" description="css" name="css">
  <highlighting>
    <options>
      <option name="LINE_COMMENT" value="" />
      <option name="COMMENT_START" value="/*" />
      <option name="COMMENT_END" value="*/" />
      <option name="HEX_PREFIX" value="" />
      <option name="NUM_POSTFIXES" value="" />
      <option name="HAS_BRACES" value="true" />
      <option name="HAS_PARENS" value="true" />
    </options>

  </highlighting>
  <extensionMap>
    <mapping ext="css" />
  </extensionMap>
</filetype>

You can create a new syntax definition via Settings / Editor / File and Code Templates.

Alternatively create a javascript.xml file in C:\Users\%USERNAME%.PyCharm30\config\filetypes with this content:

<?xml version="1.0" encoding="UTF-8"?>
<filetype binary="false" default_extension="" description="Javascript" name="Javascript">
  <highlighting>
    <options>
      <option name="LINE_COMMENT" value="//" />
      <option name="COMMENT_START" value="/*" />
      <option name="COMMENT_END" value="*/" />
      <option name="HEX_PREFIX" value="" />
      <option name="NUM_POSTFIXES" value="" />
      <option name="HAS_BRACES" value="true" />
      <option name="HAS_BRACKETS" value="true" />
      <option name="HAS_PARENS" value="true" />
      <option name="HAS_STRING_ESCAPES" value="true" />
    </options>
    <keywords keywords="break;case;catch;class;const;continue;debugger;default;delete;do;else;export;extends;finally;for;function;if;import;in;instanceof;let;new;return;super;switch;this;throw;try;typeof;var;void;while;with;yield" ignore_case="false" />
  </highlighting>
  <extensionMap>
    <mapping ext="js" />
  </extensionMap>
</filetype>
