In web page production, we often encounter such a problem: once the resolution is larger and the window is maximized, the layer is misaligned. When you insert a layer with a menu, the layer is positioned relative to its parent element, and as soon as you move it, it immediately becomes absolute.

Although this problem is small, it will still cause some trouble for web designers in the actual application process.

In fact, the core of the layer misalignment is the problem of the parent layer and the child layer. As long as the parent layer is positioned relative to a certain point, and the child layer is positioned relative to the parent layer, the goal of relative positioning of the layer can be achieved.

First, insert ** in the page (you can set it to center), click the mouse in a cell, and then insert a layer through the menu, and the layer will be positioned relative to this cell. After inserting a layer, don't touch it, and never move it, but you can change its size, for example, to "0" in height and width, so that it doesn't affect your other content, otherwise, the "left" and "top" attributes of this layer will become absolutely positioned. If it becomes an absolute positioning, you can remove its "left" and "top" attributes and revert to relative positioning.

After becoming "0", sometimes the sublayer will be invisible, you can press the "F11" key to restore it. Now the cursor should flash within this layer, and then insert the sublayer via the menu, at which point the sublayer overlaps the parent layer, and you can move it around as you like.

No matter how it moves, it is positioned relative to the parent layer. At this point, the problem is solved. Be careful not to move the "left" and "top" attributes, though, as they are positioned relative to the top left corner of the parent layer.

Tip: Insert a ** first, insert the parent layer in one of the cells, you can make it smaller, say 20 pixels wide and 10 pixels high, so that it will not cover the links below and will not affect the relative positioning of the sub-layers. If you want to define ** with a width of 778 pixels, you can insert the parent layer into the first cell of the first row of **, so that you can insert the mother layer after all the layers are made!

Just set the alignment of the layers to absolute.

1. Many of them are damaged by moisture or aging of the keyboard itself, so try to replace the keyboard.

3. Other factors are also possible, such as: there is a problem with the line, the motherboard is damaged, and the CPU is not working properly.

5. There is also a situation where the high nuclear condition is a system problem, and it will be fine to reinstall the system!

1. The number of cores is the number of computing control units made on the CPU, you don't look at the chip is very large, in fact, the really useful circuit part is less than a nail piece, you can put a core or multiple cores on it, they may share resources such as cache. The number of threads is the number of threads that can run at the same time, and the number of cores and threads are the same, but because Intel has engaged in hyper-threading technology, so that two threads can run at the same time on a core, which is different from the number of cores.

2. Hyper-threading is to make a control unit outside the core to virtual another core, and the control unit rearranges the instructions, so that when the two virtual cores execute different instructions, different parts on the physical core can work at the same time, which is equivalent to two cores, but in some cases, such as when the same instruction is executed at the same time, the two virtual cores will crash, so theoretically, this virtual dual-core is not as good as the physical dual-core. However, in fact, due to the different optimizations of each CPU for instruction execution, caches, other peripheral facilities, etc., it is difficult to generalize.

3. The open core is mainly for AMD CPUs in the early years, when AMD made some 3-core products, in fact, there were 4 cores in them, just for marketing means to shield one of the cores, and someone cracked this shield, called open core. For AMD, there is no big cost difference between 3 cores and 4 cores when they are directly manufactured, and in order to reduce some other costs, 3 cores are generally cropped from 4 cores. It seems that the AMD CPU produced now has no possibility of opening the core

Everyone understands the number of cores, the number of threads, as an analogy, there is a [dual-core 4 threads, cache 3M, main frequency 2G CPU], it uses its own resources to simulate another self, just like a ninja, but the one that is not as strong as the real body. Therefore, dual-core and 4-thread it is not as good as [4-core, 4-thread, 3m 2g]. However, it is stronger than the CPU of [4 cores, 4 threads, 512k 1G].

CPU performance comparison is also related to the main frequency and cache. There is no comparison with what the landlord asked. i3 dual-core 4-thread, I think it's cooler than AMD640's 4-core 4-thread. The first is that the architecture is better, and then the cache is much better than the 640.

For example, he wanted to make a 4-core and 4-thread, but one of the cores couldn't run stably, so he banned that core and turned it into 3 cores and 3 threads. Those masters bought this and went back to open the core, and opened it into 4 cores and 4 threads, but they couldn't be sure if it could work normally. Some are unstable, and in the end they have to be changed back to 3 cores.

The GPU is a GT 635M low-end GPU.

To play big games with at least GT650M on the GPU.

You can refer to the appearance of Lenovo Y400 **4800.

What do you mean by your big game??? However, the now popular CF, LOL, can all work perfectly.

Yes, my book is this model. Let's do it.
