    The interior of a star generally produces continuum radiation, with no visible spectral features. The absorption lines you see in stellar spectra are actually due to that continuum light passing through elements in the cooler outer layers of the star.

    After browsing the site, im still unsure for the answer :
    then how did they detected 90% hydrogen and Helium, at first place? if " "
    is there any chances of them (scientists) detecting any more elements if it is not the line spectrum? (I am annoying I know, but please try to help me comprehend this, will ya?)
