What is the ebsco page layout setting?
Ebsco web page layout generally has the following seven steps:
1. Page size: The page size is related to the size and resolution of the display. The limitation of the web page is that it can't break through the range of the monitor, and because the browser will take up a lot of space, the range of the left page will become smaller and smaller. When the general resolution is 1024×768, the display size of the page is1007× 600; When the resolution is 800×600, the display size of the page is 780×428 pixels; When the resolution is 640×480, the display size of the page is 620×3 1 1 pixel. As can be seen from the above data, the higher the resolution, the larger the page size.
It's huge. The browser toolbar is also the reason that affects the page size. At present, browser toolbars can be cancelled or added, so when displaying all toolbars and closing all toolbars, the page size is different.
In the process of web page design, dragging the page down is the only way to add more content (size) to the web page. Remind the family. Don't let visitors drag the page more than three screens unless you are sure that the content of the website can attract people to drag. If you need to display more than three screens on the same page, you'd better make internal page connections on them to make it easier for visitors to browse.
2. Overall modeling: What is modeling? Modeling is an object image created. The overall image of the page should be a whole, and the combination of graphics and text should be orderly and organically unified. Although both the monitor and the browser are rectangular, we can make full use of other shapes and their combinations in nature: rectangle, circle, triangle, diamond and so on.
For different shapes, they represent different meanings. For example, rectangles represent formality and rules, and it is noted that many ICP and government web pages are shaped by rectangles as a whole; The circle represents softness, unity, warmth, safety, etc. Many fashion websites like to use a circle as the overall shape of the page; Triangle represents strength, authority, firmness, aggression, etc. Many large commercial websites often use triangles as the overall shape of their pages to show their authority. The diamond represents balance, harmony and fairness, and some dating websites often use the diamond as the overall shape of the page. Although different shapes have different meanings, most of the current web pages are composed of multiple shapes, of which one shape is the main one.
3. Header: A header can also be called a header, and its function is to define the theme of the page. For example, most names of websites are displayed in the title. In this way, visitors can quickly know what this website is about. Header is the key to the whole page design, which will involve more designs below and the coordination of the whole page. Website name, company logo, banner advertisement and other pictures. Usually put in the header.
4. Text: Most texts are displayed as "lines" or "blocks" (paragraphs) on the page, and their positions determine the visibility of the whole page layout. In the past, due to the limitation of page making technology, the flexibility of text placement was very small, but with the rise of DHTML, text can be placed anywhere on the page according to its own requirements.
5. Footer: Footer echoes the header. The header is where the theme of the website is placed, while the footer is where the manufacturer or company information is placed. As you can see, a lot of information is put in the footer.
6. Pictures: Pictures and words are two elements of a web page, but both are indispensable. How to deal with the position of pictures and words has become the key to the layout of the whole page. And layout thinking will also be reflected here.
7. Multimedia: Besides words and pictures, there are other media such as sound, animation and video. Although not often used, with the rise of dynamic web pages, they become more important in web page layout.

How to measure fillet radius?
This problem can be transformed into the problem of finding the radius of an arc. Take any two points on the arc as tangents, then the tangent point is perpendicular to the tangent, and the two perpendicular lines intersect at one point, which is the center of the circle. Then measure the distance from any point on the arc to the center of the circle, which is the radius of fillet.

Fish fillet patent:
Many of Apple's previous patents on iPhone and iPad will more or less contain some practical functions, such as Home button, back contour design or integral glass cover design of front panel.
But the patent obtained this time only describes the appearance design of a device, with rectangular rounded corners. The application scenario of this patent is really too wide. Of course, you can say that the patent figure restricts this patent to devices with a specific aspect ratio, so that other sizes and proportions of flat plates can still not infringe.
