pseudo-class

Consider the following HTML: <div class="a"> <div class="b">Hello</div> </div> <div class="c"> <div class="b">World</div> </div> Adding the following CSS colors only "World" in red, as expected: .c .b { color: red; } But, adding the following CSS instead colors both "Hello" and "World" in red : :not(.a) .b { color: red; } Why? You need to give it like this:- Demo div:not(.a) .b { color: red; } Pseudo-class :not Syntax is selector:not(){ properties } Since the :not pseudo-class represents an element that is not represented by its argument, you have to specify the element you want to exclude

I have a flyout menu where at the end of "Quick Links" I use the :after pseudo-element on the first LI tag to display an icon from a sprite file. The HTML: <ul class="rs-quick-links-nav"> <li> <a href="#">QUICK LINKS</a> <ul> <li><a href="#">Enhanced Recipe Search</a></li> <li><a href="#">Recipe Collections & Favorites</a></li> <li><a href="#">Cooking Tips & Techniques</a></li> <li><a href="#">Shopping & Storing</a></li> <li><a href="#">Tools & Products</a></li> <li><a href="#">New Uses for Old Things</a></li> <li><a href="#">Guide to Ingredients</a></li> </ul> </li> </ul> The CSS: .rs-quick

My team was debating what the best practice would be for wanting to insert an icon after links to the various media file types we have on our site. Examples would be linking to a PDF and wanting to insert an icon image to let users know it's a PDF. The same could be used for video or audio files. I suggested using CSS, putting a class on the and using :after to create an element. I recall IE6 and IE7 won't support the pseudo CSS class, but aside from that, would there be a better practice? If the links were in an unordered list, I know the icon image could be used to replace a bullet character

I have some HTML that looks like this: <div class="SomeContainer"> <div class="MyClass"></div> <div class="MyClass"></div> <div class="MyClass"></div> <div class="MyOtherClass"></div> </div> And I use the following CSS .MyClass{...} .MyClass:last-child{box-shadow:0px 5px 10px black;} I wrongly assumed that last-child operated on the last child of a certain class but it actually operates on the last-child of the container if it's of the same class. Is there some convenient way around? I know I could add a wrapper around the MyClass div and add the CSS for the shadow to the wrapper but I was

This question already has answers here : Why does .foo a:link, .foo a:visited {} selector override a:hover, a:active {} selector in CSS? (3 answers) Closed 3 years ago . I‘m study CSS in the "w3schools", in the chapter of "link", they say: "When setting the style for several link states, there are some order rules: a:hover MUST come after a:link and a:visited a:active MUST come after a:hover" I want to know why the correct order is L.V.H.A, not L.H.V.A or another. Pseudo-classes must be declared in a specific order. The mnemonic L o V e HA te is always useful for remembering the correct order:

I am struggling to get a simplest css hover pseudoclass to work. Anybody knows why the following doesnt work? the css #hidden {display:none;} #show:hover #hidden{display:block;} the html <a href="#" id="show">show</a> <div id="hidden">here i am</div> I really feel stupid asking such a simple question, i did this a hunderd times, but cant figure out why this shouldnt work. Try this #show:hover + #hidden{display:block;} :hover #hidden implies that #hidden is a child of the hover element. The + selector looks for the next adjacent sibling. 来源： https://stackoverflow.com/questions/3847568/css

So we're required to use the following order for CSS anchor pseudo-classes a:link { color: red } a:visited { color: blue } a:hover { color: yellow } a:active { color: lime } But my question is why bother with the a:link part? Rather, is there any advantage to the above (other than perhaps clarity) over: a { color:red; } /* notice no :link part */ a:visited { color: blue; } etc.,etc. :link selects unvisited links, that is: anchors with an href attribute which have not been visited by the browser (for whatever definition the browser vendor has for "visited"). If it has :link then it will never
