Poem of html

从前有个人叫小高
他说写 HTML 感觉最好
但他写的代码结构语义一团糟
他写的标签谁也懂不了。

Violet Evergarden the first episode

Summary

Raised as a cold, emotionless "weapon" in a brutal war, a young girl named Violet loses both her arms and her beloved commander, Gilbert. In his final moments, Gilbert tells her, "I love you."

Unable to understand the meaning of these words, the war-torn Violet later becomes an "Auto Memory Doll"—a ghostwriter who pens heartfelt letters for people who cannot express their own feelings.

The Solar System in a Table

Time stamp: 2026-07-04

Here is a quick reference table for the eight planets in our solar system. The values are rounded for simplicity.

Planet Diameter (km) Distance from Sun (million km) Moons Day Length Year Length Atmosphere Notable Feature
Mercury 4,880 58 0 59 Earth days 88 Earth days Extremely thin Smallest planet; fastest orbit
Venus 12,104 108 0 243 Earth days 225 Earth days Thick CO₂ Hottest planet; spins backwards
Earth 12,742 150 1 24 hours 365.25 days Nitrogen & Oxygen Only known planet with life
Mars 6,779 228 2 24.6 hours 687 Earth days Thin CO₂ Largest volcano: Olympus Mons
Jupiter 139,820 778 95+ 9.9 hours 11.9 Earth years Hydrogen & Helium Great Red Spot; largest planet
Saturn 116,460 1,434 146+ 10.7 hours 29.5 Earth years Hydrogen & Helium Prominent ring system
Uranus 50,724 2,873 27 17.2 hours 84 Earth years Hydrogen, Helium, Methane Rotates on its side
Neptune 49,244 4,495 14 16.1 hours 165 Earth years Hydrogen, Helium, Methane Strongest winds in the solar system

A few takeaways: the inner planets (Mercury, Venus, Earth, Mars) are small, rocky, and close to the Sun. The outer planets (Jupiter, Saturn, Uranus, Neptune) are giant worlds made mostly of gas or ice, with many moons and ring systems. Even with rounded numbers, the size gap between Earth and Jupiter is astonishing.
