When describing someone or something in Spanish, the adjective *almost always* comes after the noun. The important phrase to remember here is almost always - as with many rules in Spanish, there are a few exceptions. This article will discuss those few anomalies and identify adjectives that can be placed before the noun they modify.
When describing the qualities of someone or something we admire, the adjective often times comes before the noun it modifies. When translating into English, you can think of it as adding "really" before an adjective.

Es un bonito día. → It's a (very) beautiful day.
Es una gran mujer. → She is an amazing woman.
To add a poetic undertone or an extra sense of emotion, adjectives can be put before the noun they modify. This style is mostly found in literature, however you may also hear it when someone is trying convey their emotions towards someone or something.
La blanca nieve → The white snow.
Una mala noticia. → Terrible news.
Los dulces sueños. → The sweet dreams.
La hermosa vista. → The beautiful view.
