(1) Study Notes for the entries of Baidu frontend Technical College in the spring of 2017 and those for the second quarter of 2017

Last year, I made an IFE question. This year, I joined the competition with people. Here, I wrote some notes to record my problems and learning experiences, and updated them occasionally.

It may not be made by myself. Many of them are contributed by their teammates and should pay tribute to them for their learning ~

 

Warm-up:

Registration is now just starting. It was officially launched in February 24 and has four warm-up questions.

Step 1: Find the next link: select all the pages or directly find the elements on the console, and find the hidden white address. Ask the teammates to know that the address uses base64 encryption. After decryption, go to step 2.

Step 2: Find the height of the 'window': When the scroll wheel is 521 displayed on the page, manually adjust the height of the window to 521px to enter step 3 (there are other methods, manual is the least technical)

Step3css moves the letter to the specified position: absolute; left/top values are adjusted slowly, which involves the transform: scale and rotate transformations of css3.

Transform: scale (x, y); defines scaling. 0. a or 1. a indicates narrowing down or enlarging, 1 indicates not changing, and-1 indicates turning.

Transform: rotate (angle); defines rotation, in the unit of deg,-30deg indicates counter-clockwise rotation

Transform: scale (x, y) rotate (angle); both applications must be written in the same transform by spaces.

Step 4: control the ball to eat stars: The mouse clicks will console the coordinate values of x and y, so as to use the prompt to move the ball. The ball's API can be guessed by the prompt and can also be console

For (var x in ball ){

Console.info (x );

}
