The issue I'm running is that, for example if I shrink my screen down to be tiny, the gutters end up being wider than the columns themselves, as seen below (darker blue = column, lighter blue = gutter). Can you modify the gutter width of certain resolution states? (mobile, tablet, etc) 回答1: The gutter is construct by a left and right padding, you could use media queries to change this depending on your screen size: /* Small devices (tablets, 768px and up) */ @media

Example: Link.............Chapter 1 Link.............Chapter 2 Link.............Chapter 3 回答1: taken from catchmyfame : "How is this done? Basically field label is wrapped in a div which has a small image of a dot applied repeatedly in the x direction as a background. This alone would cause the dots to flow under the text so to nullify that effect, the text itself is then wrapped in a span where the background color is set to match the color of the background of the

Is this standard for YouTube videos or is there something that I can add to the code to make it go smaller? 回答1: You can make YouTube videos responsive with CSS.

Here's my code: $body_padding: 50px body padding-top: $body_padding height: calc(100% - $body_padding) If I use the literal 50px instead of my body_padding variable, I get exactly what I want. However, when I switch to the variable, this is the output: body { padding-top: 50px; height: calc(100% - $body_padding); } How can I get Sass to recognize that it needs to replace the variable within the calc function? 回答1: Interpolate: body height: calc(100% - #{

I'd like to do it in pure CSS, are there any methods? 回答1: If the parent element has a solid color background, you can use pseudo-elements to create the effect: div { height: 300px; background: red; position: relative; } div:before { content: ''; position: absolute; top: 0; right: 0; border-top: 80px solid white; border-left: 80px solid red; width: 0; } http://jsfiddle.net/2bZAW/ P.S.

Is there any difference between them? 回答1: They're the same thing (in API Level 8+). Use match_parent . FILL_PARENT (renamed MATCH_PARENT in API Level 8 and higher), which means that the view wants to be as big as its parent (minus padding) ... fill_parent : The view should be as big as its parent (minus padding). This constant is deprecated starting from API Level 8 and is replaced by match_parent . http://developer.android.com
