In a design where text needs to appear as though it is glowing, what CSS property should be used to create this effect, and how should it be manipulated to achieve the glow?
- text-shadow: 0 0 10px rgba(255, 255, 255, 0.7);
- color: #fff; text-shadow: 0 0 5px rgba(255, 255, 255, 0.7), 0 0 10px rgba(255, 255, 255, 0.7);
- font-color: #fff; text-shadow: 0 0 10px rgba(255, 255, 255, 0.7);
- text-shadow: 0 0 5px rgba(255, 255, 255, 0.7), 0 0 10px rgba(255, 255, 255, 0.7);
