I made a black/transparent pattern for the circle and set it to :before. The circle is then transformed rotate(180deg) and moved … Read more
You can do it with table style CSS properties, but still retain table less markup (which is still a win). Example HTML <div id=”container”> <div id=”header”><div>header</div></div> <div id=”content”><div>content</div></div> <div id=”footer”><div>footer</div></div> </div> CSS html, body { height: 100%; padding: 0; margin: 0; } #container { display: table; width: 100%; height: 100%; border: 1px solid red; text-align: … Read more
The issue here is not line height but vertical placement of glyphs, in particular the location of the text baseline. That’s something that the font designer has decided on; the designer draws glyphs and places them in the em square, the conceptual device that has height equal to (or defined to be) the font height. … Read more
Bootstrap accomplishes the transition animation of the responsive nav bar the same way it does any collapse, which is using a CSS3 transition. To turn off the transition for only the navbar (leaving any other transitions in place), you simply have to override the CSS. I’d suggest adding a class, such as no-transition (but the … Read more

But these can be overridden in CSS. The difference in the way text-align:center works between the two is down to the width. A block element defaults to being the … Read more
Neither HTML or CSS have any concept of when descendants of a container wrap. Essentially, the browser renders the document during an initial cascade. It does not reflow the document when a child wraps. Therefore, to change the number of columns, you will need to set a width limit somewhere along the line or use … Read more
As far as I know, CSS doesn’t offer any selectors which will target before a selector. Could you select it as an h2 which is directly after a p (p + h2)? h2 { color: #1a1a1a; } p + h2 { color: #0cc; } Example on JSFiddle As you can see, this is probably the … Read more
Vertical-Align vertical-align is used to align inline-level elements. These are elements, whose display property evaluates to: inline inline-block inline-table (not considered in this answer) Inline-level elements are laid out next to each other in lines. Once there are more elements than fit into the current line, a new line is created beneath it. All these … Read more
You will have to use a CSS preprocessor to do this. SASS placeholder %rounded-corner {} %corner {} %button-effective {} .button { @extend %rounded-corner; @extend %corner; @extend %button-effective; /* Some other styles. */ } .box { @extend %rounded-corner; } Compiles to: .button, .box { /* rounded-corner styles */ } .button { /* corner styles here */ … Read more
