Child element Selector

Select the element's child element,

Different from descendant selectors: #choose_car option; option is not necessarily a child element

For example #choose_car > option footer > P; > must be a direct child element

Can be many levels: UL > Ol > Li > Em

Group selection

Group selection Select multiple elements at the same time, comma separated syntax: <s1>,<s2>

Like P,button #food,. Cheese

Combined use

Select all the span child elements with the ID food and all P (including non-food child elements) #food > Span, P- group selected with lowest priority

Select all the span child elements with the ID food and all the P child elements #food > span, #food > P

Select all child elements with ID food #food > *

Brother Node Selection

Select the element immediately following the other element, which has the same parent element, such as #food + div; #many > div > p.special + P immediately following the sibling node

Select the element after the other element, which has the same parent element, such as #food ~ Div, all the sibling nodes

Property Selector

Elements can be selected based on their attributes and attribute values

Like what

*[style]

P[SPEC=LEN2]

p[spec= ' Len2 Len3 '] in the middle of the space, so add quotation marks, no spaces, can be added without

P[spec*= ' Len2 '] #包含

P[spec^= ' len2 '] #开头 end

P[span$= ' Len2 ']

P[CLASS=SPECIAL][NAME=P1] satisfies both properties

Http://www.w3school.com.cn/cssref/css_selectors.asp

P:nth-child (2) Select each <p> element that belongs to the second child element of its parent element

P:nth-last-child (2) ibid., starting with the last child element count.

P:nth-of-type (2) Select each <p> element that belongs to the second <p> element of its parent element

P:nth-last-of-type (2) ibid., but starts counting from the last child element

Verify the CSS selector, click Elements, press CTRL +F
