The moon is about 400 times smaller than the sun, but the sun is about 400 times further away, so from our viewpoint on earth, they appear the same size in the sky. Coincidence or designed that way? - well that's another discussion...
You can draw a diagram with the Sun at one side, the Moon in the middle and the Earth on the other side. A shadow falls on the Earth and anyone on that part of the Earth sees a solar eclipse. Obviously the Moon is not that big, so when there is an eclipse on one part of the Earth, other people in many different places don't see one.
In a lunar eclipse the Earth is in the middle and blocks the Sun's light from the Moon, so that happens always at Full Moon but not every time. A solar eclipse has the Moon in the middle so it happens at New Moon, but not every time, and the Moon is not big enough to shadow the whole Earth so a solar eclipse is seen only in a strip across the Earth's surface.
The path of totality for a solar eclipse is different for every eclipse, because even tiny changes in the alignment of the Earth and Moon make a big difference. The NASA eclipse web site calculates the path for each eclipse, at the link below.

You can see a total solar eclipse when the moon passes directly between the Earth and the Sun, completely blocking out the Sun's light. This phenomenon can only be observed in specific areas where the alignment of the Sun, Moon, and Earth is precise.

The Moon is in an elliptical (or oval-shaped) orbit. When a solar eclipse occurs near apogee, when the Moon is farthest away from the Earth, the apparent size of the Moon is smaller than the apparent size of the Sun. So we get an "annular" eclipse.

The 'big black disc' that move over the face of the Sun is the Moon during a partial or full solar eclipse.
You can see a total solar eclipse when the moon passes directly between the Earth and the Sun, completely blocking out the Sun's light. This phenomenon can only be observed in specific areas where the alignment of the Sun, Moon, and Earth is precise.
Solar eclipses occur when the Moon and Sun lie on the same line of sight from the standpoint of a terrestrial observer. Naturally, there are two types of solar eclipses: partial and total. The Sun and Moon have about the same angular size (they take up the same amount of area on the celestial sphere as seen from Earth), so in order to have a total eclipse, the alignment of Sun, Earth, and Moon must be just right for the right observer. It is also worth noting that the Moon's shadow is not as big as the Moon; it shrinks proportional to the square of the distance between it and whatever object it's casting its shadow upon (in this case, the Earth). Total solar eclipses are both very rare and subjective. That is to say that there is only a small area on the Earth where one can observe a total solar eclipse when one occurs. Others will see a partial eclipse.
During a lunar eclipse, the Earth comes between the Sun and the Moon, casting a shadow on the Moon. This causes the Moon to appear dark or reddish in color. In contrast, during a solar eclipse, the Moon comes between the Sun and the Earth, blocking the Sun's light and casting a shadow on the Earth. This results in the Sun being partially or fully obscured, creating a darkened sky during the day.
There are 4 types of solar eclipse. Total, Hybrid, Annular and Partial eclipses.A Total Eclipse is when the sun totally covers the sun.An Annular Eclipse is when the whole moon is in line with the sun but the apparent diameter of the moon is less than the apparent diameter of the sun.A Hybrid Eclipse is when some places on Earth experience a annular eclipse and other places see a total eclipse.A Partial Eclipse is when the moon is not totally in line with the sun and only eclipses part of the sun.
Be cause the moon is not as big as the sun. So only the size of the moon is shadowed on earth and where the sun peaks out from behind the moon it will be perfectly light.
The moon's position is constantly changing in relation to the sun as it orbits around the Earth. Depending on the phase of the moon, its position relative to the sun can vary from being on the same side as the sun (new moon) to being on the opposite side (full moon).
