Javascript 如何包装属于一个类的一组元素以适应其父元素？
好的，我有一个部分，里面有不同的元素，比如一个数字和一个p。我目前的问题是，我尝试使用flex wrap和CSS中的所有其他包装来包装这些元素，但不知怎么的，它没有起作用，文本只是超出了部分 我将一个名为“s1”的类中的元素关联起来，我需要将它与一个名为“sec1”的类匹配到一个节或其父类中。我需要把它们分成3列 小提琴： CSS: HTML: 更改：Javascript 如何包装属于一个类的一组元素以适应其父元素？,javascript,jquery,html,css,Javascript,Jquery,Html,Css,好的，我有一个部分，里面有不同的元素，比如一个数字和一个p。我目前的问题是，我尝试使用flex wrap和CSS中的所有其他包装来包装这些元素，但不知怎么的，它没有起作用，文本只是超出了部分 我将一个名为“s1”的类中的元素关联起来，我需要将它与一个名为“sec1”的类匹配到一个节或其父类中。我需要把它们分成3列 小提琴： CSS: HTML: 更改： .main { display:flex; flex-direction:row; justify-content:sp

Driven by the doctrine of manifest destiny, the United States embarked on a vigorous expansion across North America throughout the 19th century.[23] This involved displacing native tribes, acquiring new territories, and gradually admitting new states.[23] The American Civil War ended legal slavery in the country.[24] By the end of the 19th century, the United States extended into the Pacific Ocean,[25] and its economy began to soar.[26] The Spanish–American War and World War I confirmed the country's status as a global military power. The United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, and as a permanent member of the United Nations Security Council. The end of the Cold War and the dissolution of the Soviet Union left the United States as the sole superpower.

The United States is a developed country and has the world's largest national economy.[6] The economy is fueled by an abundance of natural resources and high worker productivity.[28] While the U.S. economy is considered post-industrial, it continues to be one of the world's largest manufacturers.[29] The country accounts for 37% of global military spending,[30] being the world's foremost economic and military power, a prominent political and cultural force, and a leader in scientific research and technological innovations.
