问题 This question already has answers here : Targeting flex items on the last or specific row (3 answers) Closed 2 years ago . We have flex container with 2 child elements. When we resize window, and one of flex item wraps, we have each element on its own row. Is it any selector like :when-alone-in-row ? .flex-parent {flex-flow: row wrap} .flex-child .flex-child 回答1: No, there is no selector similar to :when-alone-in-row . However, when you want to select the first and last elements from a group

问题 This question already has an answer here : Make flex items take content width, not width of parent container (1 answer) Closed 2 years ago . I would like to have the flex children rendered inline-block so that border-bottom is under the li 's width instead of the container's width. Apparently flex children can't be set as inline-block? Is there a workaround to this problem? .menu { display: flex; flex-flow: column; list-style: none; padding: 0; } .menu > li { display: inline-block; margin

问题 I'm trying to build an unordered list something like this: - Item 1 | - Item 4 - Item 2 | - Item 5 - Item 3 | - Item 6 I have this HTML: <div class="multi-column"> <ul> <li>Item 1</li> <li>Item 2</li> <li>Item 3</li> <li>Item 4</li> <li>Item 5</li> <li>Item 6</li> </ul> </div> and this CSS: .multi-column { -moz-column-count: 2; -moz-column-gap: 20px; -moz-column-fill: auto; -webkit-column-count: 2; -webkit-column-gap: 20px; -webkit-column-fill: auto; column-count: 2; column-gap: 20px; column

问题 In this codepen example: http://codepen.io/DrYSG/pen/ovctn I created three flexboxes. The effect I want is that when one hovers over the middle box, it grows in size (color change in the demo is just to help me know about the hover). In FireFox v19 this almost works correctly. But it is strange what it picks of the start and end widths of the animation. In Chrome v25, I am getting rapid unstable oscillation of states (flashing). Really not correct. In IE10 I get the same transition as FireFox

问题 I'm experimenting with CSS Grids, and this is the layout I'm building: .grid { display: grid; align-items: center; grid-template-columns: 1fr 4rem 1fr; grid-template-rows: 1rem 1fr 1rem; max-width: 900px; margin: 0 auto; } .text { /* // Ideally, this should be grid-area: text */ grid-column: 1 / 3; grid-row: 2 / 3; /* Fix z-index */ position: relative; padding: 4rem; background-color: #fff; } .image { /* // Ideally, this should be grid-area: image; */ grid-column: 2 / 4; grid-row: 1 / -1;

问题 I am trying to generate a menu like the following: There are several items in the menu and the active one has an arrow after it. The menu items are tags like the following code: <div class="menuCenter"> <div class="linksWrapper"> <a href="#">Home</a> <a class="menuCenterLinkLeft" href="#">Plans & Pricing</a> <a class="menuCenterLinkLeft" href="#">Sign In</a> <a class="menuCenterLinkLeft active" href="#">Sign Up</a> <a class="menuCenterLinkLeft" href="#">Contact</a> </div> </div> I tryied two

问题 Essentially this is what I'm getting... While this is what I want. I have the image height and width set up like this... #content img{ padding: 3%; width: 60%; height: 50%; float: left; } With %s as I want it to be responsive and all. So the exact height of the image in px I can't really tell. When I try to set up the same dimensions for the gray box, it only fills up with what is in it as you can see. #text{ padding: 3%; margin-right: 3%; margin-top: 3%; width: 37%; height: 50%; float: left;

问题 I have a box in one of my websites that has a these property: -moz-box-shadow:inset 0 0 50px #ecf4de; -webkit-box-shadow:inset 0 0 50px #ecf4de; box-shadow:inset 0 0 50px #ecf4de; This gives the box a nice gradient towards the center. However, Safari does not support the "inset" property and IE doesn't support box-shadow at all. I can't use an image for this because the height of this box changes for each situation. I don't want to use 3 images, (one for the top, a repeating one for the

问题 I'm trying to calculate the right scale to apply to children inside a parent but i can't use calc() inside transform: scale CSS function. I've done this function with javascript but i'm interested in a pure CSS solution to avoid bloating the page with scripts as much as possible. Example: CSS .anyclass{ height:250px; /*this value can change dinamically */ transform:scale(calc(100% / 490 )); /*is using height value*/ } This definition gives back an invalid property value. Other uses like
