Thank you verymuch, I have changed it . but I had another problem I did not expected. the blogs in Homepage priviously 3 are in one row, right now it turned to be 1 in one row which seems very agly. I did not change anywhere at all, I did not know how it happend. it happened by suddden. This is may be the last question on this theme. please have a look at. thanks for your help.
