front-end vue
Here is the front-end component of vue scaffolding, which is divided into two divs. First, the first div is at the top, accounting for 1/20 of the height of the screen, and the width is self-adaptive. The entire div has a prominent shadow effect, and the background is not modified, white By default, the leftmost part is the prominent yellow label of the "Examination Bank Management System", and the rightmost part has the "candidate" avatar, the "candidate" label, and the "logout" red button. Then the second div is divided into two divs, which are displayed under the first div. The width of the div accounts for 80% of the screen and the center is aligned. The first div is some option navigation, and the height is the same as the first div. , left and right two lable tags-type", which are option tags, all, preparing for the exam, completing the exam, not yet the exam time, then type, ready to sort, start time, exam time, the second div includes some div-boxes, 4 in each row, 3 rows full of design, and these div boxes are divided into two layers, the top is "*** midterm exam" and then filled with a certain color, and the bottom is some exam information labels, including start time, and Exam time information. Finally, there will be a button at the bottom right of each small div. These buttons will be changed according to the situation. For example, the default is "Start Exam".
third page
Help me organize the layout again. Now the tabs occupy the entire lower half of the screen. In fact, it should be on the left, accounting for 60% of the entire screen. On the right, there should be single-choice questions, multiple-choice questions, and judgment The tabs of the question are arranged in vertical rows and occupy 30% of the entire screen
The modes of multiple-choice questions, multiple-choice questions, and judgment questions should be arranged vertically and separated. Their tabs should be blank boxes, not themselves. Do you understand what I mean?
Please give me the code if you understand what I mean
