Flat Design Text Size Adjustment Icon Animation

This minimalist animated icon features a black outline 'T' enclosed within a square, symbolizing text content. Below this central element, a dynamic horizontal line segment smoothly transforms into a pair of outward-pointing arrows, indicating expansion or adjustment, before reverting to its initial state. The animation is clean, crisp, and presented in a flat design style against a stark white background. This versatile visual asset is perfect for user interface elements, application demonstrations, or explainer videos requiring clear and concise representation of text formatting options, character spacing, or responsive sizing adjustments within digital media.
