We can change the automatic behaviour of what order our grid items appear. We can even re-order the items in our grid to fill available space using the dense keyword. How do we approach this using grid-auto-flow? By default 'grid-auto-flow' is 'row'.…
最近看到几篇博文讲解margin:auto在flex容器中的使用,可惜的是大多讲解都浮于页面表现,没深究其中的作用机理,本文在此浅薄对其表现机理做简单探讨. 引子 日常业务迭代过程中,flex已经是前端工程师解决常见布局的神兵利器.但是随着使用的深入,偶然会发觉flex对于简单的布局足够直接迅速,但是对于稍稍复杂一些的布局,就需要层层的包裹分组来解决.举个栗子,下图是我们常见的布局图: 如果flex容器之中仅仅只有三个元素,彼此分离,我们借助于justify-content就足够应付.但是如果其…

As with flex items, we can set an order value on grid items. Let’s see how this affects the DOM and the appearance of our grid. <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Order&l…
It’s possible to position a grid item anywhere on a grid track. To do this, let’s specify some grid-template-columns and grid-template-rows, and to the grid items, we’ll pass grid-column and grid-row some numeric values. <!DOCTYPE html> <html lan…
关于使用text-align:center和margin:0 auto 两种居中方式的比较 前言:最近由于要学习后端,需要提前学习一部分前端知识,补了补css知识,发现狂神在讲这一部分讲的不是特别清楚,于是自己决定试一试 1.需要先了解块级元素和行间元素 块级元素有:div(div默认是块级元素),p标签,h1-h6等: 行间元素有:a标签,img标签等 两者区别就是,块级元素可以独占一行,之后的默认存在换行符,行间元素可以多个处于一行内,只有超过外部边框的时候会换行. 2.问题的引出 <!DO…
Inside of a flexed container, a single item can control its own flex with align-self. The possible values are flex-start, flex-end, center, or stretch Inside column layout, the ' stretch' is also limited by the 'height'; Inside row layout, the 'stret…
We changed the axis layout with 'justify-content', and the "off axis" layout is controlled by 'align-items'. The most common values are flex-start, flex-end, or center. body { display: flex; flex-direction: row; } .container { background-color:…
