Since the first year of the public in 2012, the public has traveled 4 years, "an advertisement 200,000" "public value of 10 million" such myths, a growing number of enterprises, groups, individuals opened the public number, want to share from it.In the second half of 2015, the overall performance of the public number began to be weak, and by the year 16, the Red Sea fatigue intensified: reduced session opening rates, lower reading volumes, increased cost of access to new users, lower fan activit

water, water is also soaked with a watermelon, the room in mid-air there are a lot of hooks for hanging things. Now I put the page elements and the above object, then the room is a Web page, bucket is a page in the plate, bucket of water is text flow, watermelon is to be positioned object.

In contrast to the previous explanation, if the
).Relative positioning (relative): objects are not stackable and are offset from the normal document stream by attributes such as Left,right,top,bottom. You can also use Z-index layering design.2. Image interpretation of positioningI'm going to set up a virtual scene: There's a rectangular room with a bucket of water in it, a watermelon in the water, and a lot of hooks for hanging things in midair. Now I have the page element corresponds to the above

If length is given and is positive, the offset+length position ends at the beginning of the array. Conversely, if length is given and is negative, the count (Input_array)-|length| position at the beginning of the array ends. Consider an example:

Positioning (absolute): Drag the object assigned to this targeting method from the document flow, using left,right,top, bottom and other properties to absolutely locate the parent object closest to its nearest location setting, If the parent of an object does not have an anchor property set, or if it follows an HTML positioning rule, it is positioned as a reference based on the upper-left corner of the body object. Absolute positioning objects can cascade, cascade order can be controlled by the
