In pchome and itpower, many MD players have mentioned that MP3 is a waste sound quality, which is very one-sided. They have completely no idea about a thing before they fully understand it.

I have no interest in pop songs. I did not know who the Four Kings were for a long time in elementary school, I used to think that "Andy Lau" is the one who played the pig in "Journey to the West" (that is called Andy Ma ). I was surprised and puzzled when I saw the girls chasing the Tigers frantically. When I got to high school, I only occasionally listened to broadcast programs. But from college, I became addicted to music. If we trace it back, we should have got our first

figure ). This also leads to the padding-left of the first column and the padding-right of the last column occupying 30 PX of the total width, which leads to the page not beautiful, of course, if you need to leave a certain margin, this is a good practice. For example, the 767th rows in bootstrap.css ~ As shown in row 772nd:
.col-xs-1, .col-sm-1, .col-md-1, .col-lg-1, .col-xs-2, .col-sm-2, .col-md-2, .col
(padding), and set the negative margin (margin) for the first and last stacks) to offset the influence of the inner distance (padding ).
The bootstrap mesh system has a responsive effect. It has four types of browsers (ultra-small screen, small screen, medium screen, and large screen). The breakpoint is 768px, 992px, and 1220px.
The container (. container) has different widths for different browser resolutions: automatic, 760px, 970px, and 1170px;
.container {padding-right: 15px;padding-left:
:
.container { padding-right: 15px; padding-left: 15px; margin-right: auto; margin-left: auto; @media (min-width: 768px) { .container { width: 750px; } @media (min-width: 992px) { .container { width: 970px; } @media (min-width: 1200px) { .container { width: 1170px; }
The horizontal bars 3 and 2 indicate that the rows (. row) of the container are evenly divided into 12 equal portions, that is, columns. Each column has a "padding-left: 15px" (pink in the figure) and a "paddin
described, the container row (. Row) divided by 12 equal parts, that is, the column. Each column has a "padding-left:15px" (the pink part of the figure) and a "padding-right:15px" (The purple part of the figure). This also led to the first column of the Padding-left and the last column of the padding-right occupy the total width of 30px, resulting in the page is not beautiful, of course, if you need to leave a certain distance, this practice is good.

appropriate alignment and padding (padding ).
2. The specific content should be placed within the column container (column), and only the column can be used as a direct sub-element of the row container (. row ).
3. There is a 30px gap between the column and the column.
4. four different types of columns are provided:
In my opinion, this figure is the essence of the Grid system. Through experiments, we can find that:
When the screen width is less than 768px (small screen), the column is divided
certain amount of spacing, this is a good practice. As shown in line No. 767, line No. 772 in Bootstrap.css:
Col-xs-1, Col-sm-1,. Col-md-1, Col-lg-1, Col-xs-2, Col-sm-2, Col-md-2,. Col-lg-2,. Col-xs-3, Col-lg-3, Col-xs-4,. col-sm-4, Col-md-4, col-lg-4, Col-xs-5, col-sm-5,. col-md-5,. Col-lg-5, Col-

3. There is a 30px spacing between columns and columns.
4. Provide 4 different types of columns:
In my opinion, this picture is the essence of grid system, and through the experiment you can find:
When the screen width is less than 768px (that is, a small screen), the column is divided by the number following the. col-xs-. If no. col-xs-is defined, it becomes sing
setting Properties for columns (column). By .row setting a negative value for the element to margin cancel out the set for the .container element, it is indirectly offset by the padding column (columns) contained in row padding .
A negative margin is the reason why the following example is out of focus. The contents of the grid column are lined up.
