Css learning experience

In fact, last year I had contact with CSS.
They all follow some web tutorials.
It is used to control links, vlinks, and so on.
At that time, I thought css was just like this.
At that time, I was very concerned, because the sensory layer was not as convenient as the table.
In March, I officially started to learn css.
Only to find that some websites do not use tables and can still do very well.
In addition, css has a speed advantage for large-traffic websites.
So far, I have been studying for two months and made some pages.
Let's talk about how you feel today.
First, css code writing is often useless. Sometimes go to the classic forum to see
Go to cssplay and find that your code is very complicated. Easy and organized without high handwriting
I often think about what I think, and I have never considered the order of attributes. For example, after margin is written, I suddenly think of it, and then write a line of margin-top, which is undoubtedly a great waste of resources. More deeply, we need to consider whether margin is written into a or li or ul. There is a lack of thinking on this issue. You need to constantly learn mature code and improve your thinking level.
2. Poor foundation. The css2 manual is very easy to read. If I see an attribute, I may be very familiar with it, but I cannot remember it when I use it. You do not have enough knowledge about other syntaxes except attributes, such as selection operators, pseudo classes, and pseudo objects. I often see
*{
} I don't know what it means, and I am always confused about the flexible usage of. tb.
Third, grasp the color. This is beyond the scope of css, but it is inevitable for every Web page design. How to match the page color? I like ipod posters very much. They are very simple in several colors, coupled with the silhouette of some crazy people immersed in ipod music, which often gives a strong visual impact. In addition, many foreign web pages use distinctive colors. Even if some web pages have a lot of colors, it gives people a general sense that they are also in place. In terms of color perception, I still have a lot to go.
Fourth, details. At the beginning, I just practiced the layout and thought that the layout was okay, and the entire network was almost the same. When I was here, I finally suffered. In fact, the details cannot be relaxed at all. The color, spacing, font, and image matching of links in each topic must have a lot of knowledge. Therefore, you cannot relax in detail.
After css is learned, there is no problem in making general web pages. However, I am well aware that "the road is long and the road is long, and I will seek further help." I hope you can give me more comments and let me know what "should not" I am very grateful. ^_^
