It is usually used with four coordinate properties: left, right, top, bottom

Static

This is the default position value: static elements only follow natural processes. They are not subject to any left,right,top or bottom values.

Relative

When position is set to relative, the element can be moved according to its current position.

Tang Ming Emperor wanted to find a beautiful woman day and night, but he could not find a satisfactory one when he ruled the country for many years. Yang Xuanying has a daughter who is very delicate and beautiful, and outsiders do not know that she is extremely beautiful in the boudoir. It is difficult to abandon his natural beauty for a long time, and he will one day be chosen to be a concubine beside the emperor. When she looked back and smiled, she was so charming that the concubines of the six palaces were overshadowed one by one. In the cold spring, the emperor gave her a bath in Huaqing Pool, and the hot spring water washed her fat-like muscles and bodies. The maid helped her like a hibiscus out of the water, so enchanting when the emperor's grace was moistened.

The temples are like clouds, the faces are like flowers, wearing golden steps, and the hibiscus tent is spending a warm spring night with the emperor. Love deep spring night hate too short sleep until the day up, the king deeply in love with his children will never be early again. Bear Jun Huan to serve Jun drink all day long with no leisure, spring from the spring outing night to guard the double shadows are not separated. There were three thousand concubines in the harem who looked like goddesses, and the emperor spoiled her alone. In the golden house, Gillian made up as a coquettish waitress every night, and the drunkenness was accompanied by the spring heart.

Sisters, wives and brothers were awarded the land of Gongqing, and the brilliance of the Yang family was envied and longed for. As a result, all the parents in the world have changed their wishes, and everyone thinks that they only want to have a baby boy. The Yuyu Qiong Building of Huaqing Palace at the northern foot of Lishan Mountain towers into the clouds, and the breeze can be heard in all directions. Slow song and slow dance condensed bamboo, the king watched all day long, the desire is not enough. Suddenly the Yuyang war drum shook the palace, and the dancing geisha stopped playing the song of neon clothes and feathers.

Let's move on:

Jiuzhong city tower and palace que beacon mixed smoke and dust, thousands of troops to protect the king fled to the southwest. The Cuihua Dragon Flag waved the procession all the way and stopped again and again, and came to the Pavilion at the post station for a hundred miles from the capital. The six armies of long Wujun and Yu Lin Army had no choice but to go, and the lingering and aggrieved beauty finally lost his life in front of the horse. The ornaments on the imperial concubine's head were scattered all over the floor, and no one asked, Cuiqiao golden sparrow jade scratched her head and precious headgear one by one. The king's doting could not save him from crying into tears, and he looked back at the tragic situation of blood and tears and tears. Autumn wind Xiao Suo sweep fallen leaves loess dust has disappeared, the circle twists and turns through the plank road team boarded the sword door.

It is difficult for few people to walk along the narrow Shu road on Mount Emei, and the banners are dark and the sun is faint near dusk. The river of Shu is green and towering, and the mountains of Shushan are green and green, and the saint is sad that the imperial concubine is in love with the old love day and night. When I see the moonlight in the palace, I always feel sad and resentful, and I hear the music of the bell in the rain at night. The king of war began to drive back to the capital, and when he arrived at the horse-drawn carriage, he hesitated to leave the heartbroken man. In the desolate loess graves under the hillside of Mengmai, the beauty can no longer see her grave on the ground.

When you look at my minister, I look at you, you look at each other with tears in your clothes, and the East Wangjing is sad and let the horse go home. Back to Chang'an Palace to see the Hechi Garden is still the same, Taiye Pool on the hibiscus flower Weiyang Palace hanging willow. Hibiscus is like her face, willow leaves, like her eyebrows, how to see things can not help but touch the scene can not help but droop eyes. The spring breeze blowing peach and plum blossoms makes people sad, and the autumn rain dripping sycamore leaves is even more desolate.

The effect is as follows:

The red border moves 20 pixels from the left and 10 pixels from the top, relative to its natural position, where it should be in the correct position.

Notice that the blue paragraph has not been moved at all. By using relative positioning, red paragraphs can move freely without destroying the layout. The only inappropriate thing is that none of the elements except itself knows that the element has moved.

Absolute

When position is set to absolute, the element can be moved according to the first positioned element.

"Positioning? what are positioning elements?"

A positioning element is one whose position value is relative,absolute or fixed. Therefore, an element is located unless the location is not set or static.

The characteristic of a positioning element is that it can be used as a reference point for its child elements.

Let's imagine a simple hierarchy:

I'minpositionrelative.

I'minpositionabsolute!

Section {

Bottom:10px;/*10pxfromthebottom*/
