While Sakura has strong feelings for Sasuke throughout the series, she never tries to kiss him during this time.
The closest we see to a romantic interaction between them is when Sakura confesses her feelings to Sasuke during the Chuunin Exams, and he responds by telling her he doesn't care about her feelings.
The dynamic between Sakura and Sasuke evolves significantly in Naruto Shippuden, so keep an eye out for more romantic developments there.
