CSS magic and charm

CSS magic and charm

In fact, the first language I learned was HTML. I remember it was a freshman. At that time, I put an HTML book on the bed, DR, the brother of the bed, and I took it for a look. That book is about 50 pages, but if it is not, today Maybe will not become a software engineer. Later I learned Flash, DHTML, and CSS, but at that time I learned CSS and DHTML only a bit. Later I thought there was a future for writing programs, so I started learning C ++, VC ++, and Java. Who knows that a lot of things are so interesting. Today, maybe every programmer should gradually realize that Browser is the future operating system and platform, so the future status of HTML, XHTML, CSS, and Javascript is self-evident.

 

I have two habits of learning a new thing. I usually go to www.amazon.com to find 4-star or 5-star books in this field. Today I am very lucky to have met one,CSS The Missing Manual. This book has a Chinese translation, and I am not willing to buy it. So let's take a look at the electronic version. (I know that reading pirated books is as shameful as using pirated software, but I don't think I can do it today without reading e-books or MP3 ).

 

CSS is simple, but this book is really good (no wonder it won the Jolt Productivity Award ). I like the Style of the author. Here we record the author's point of view. HTML is essentially used to organize the content structure, not to manage the display. All display methods should be handed over to CSS. Therefore, do not use tags like <font> and <B> <I>. You should give the display function to CSS instead of HTML. In this case, I understand a lot of truth. The author spoke too well. It is really difficult for HTML to show it, so I accept the author's point of view. So I started to study CSS.

What is the focus of css learning?

CSS is white!
It is used to change HTML clothes!

Everything in it is very important!

The color changes in the solution of chemical reactions reflect the "magic world, charm chemistry ".

(1) solution X is acid
Acid
(Fill in "acid", "Alkali", "salt"), the name of reagent A is purple shirui test liquid
Purple shirui test liquid
.
(2) If X is dilute sulfuric acid and B is oxide, the chemical formula of B is
Fe2O3
.
(3) If X is dilute hydrochloric acid and C is simple, C is named iron.
Iron
.
(4) If X is dilute sulfuric acid and D is alkali, the chemical equation of the reaction between X and D is sulfuric acid + Cu (OH) 2 samples cuo4 + 2H2O.
Sulfuric acid + Cu (OH) 2 samples cuo4 + 2H2O
