size_t seems like overkill for these. I don’t think we handle those kinds of huge row and column counts. Why not just “unsigned”?

> Source/WebCore/css/CSSParser.cpp:4811
> +    RefPtr<CSSValueList> templateRows = CSSValueList::createSpaceSeparated();

Why create this just before an early return? I suggest moving this declaration down.

> Source/WebCore/css/CSSParser.cpp:4817
> +    while (m_valueList->current()) {

could write this as a do/while to avoid the redundant check at the start of the loop

> Source/WebCore/css/CSSParser.cpp:4837
> +            templateRows->append(value);

value.release() would avoid a bit of reference count churn

> Source/WebCore/css/CSSParser.cpp:4853
> +        addProperty(CSSPropertyWebkitGridTemplateColumns,  cssValuePool().createIdentifierValue(CSSValueNone), important);

Extra space here after the comma.

> Source/WebCore/css/CSSParser.cpp:4895
> +            addProperty(CSSPropertyWebkitGridTemplateColumns, columnsValue, important);

columnsValue.release()

> Source/WebCore/css/CSSParser.cpp:4896
> +            addProperty(CSSPropertyWebkitGridTemplateRows, rowsValue, important);

rowsValue.release()

> Source/WebCore/css/CSSParser.cpp:5029
> +    return values;

values.release()

> Source/WebCore/css/CSSParser.cpp:5273
> +    if (!gridRowNames.length())

isEmpty is preferred over !length

> Source/WebCore/css/CSSParser.cpp:5296
> +        for (lookAheadColumn = currentColumn; lookAheadColumn < (columnCount - 1); ++lookAheadColumn) {

Parentheses here don’t make the code clearer. I suggest omitting them.

> Source/WebCore/css/CSSParser.h:50
> +
> +

Extra space here. Just one blank line will do.

> Source/WebCore/css/CSSParser.h:77
> +#if ENABLE(CSS_GRID_LAYOUT)
> +class CSSGridLineNamesValue;
> +#endif

Not really helpful to put forward declarations inside an #if. I suggest just declaring this unconditionally.

> Source/WebCore/css/CSSParser.h:178
> +    void parseGridLineNames(CSSParserValueList&, CSSValueList&, CSSGridLineNamesValue* = 0);

nullptr
