Example-1: In this example, the element is searched by document.getElementById(‘Id’) and !! Chris, I highly appreciate your work, and would like to hear your opinion and discuss on this topic. Looking forward to your response), Yes I think everything I understood there is correct =). if parent selectors were allowed, the parser would need to travel back up the xml tree, which is exponentially slower. After working with css for a very long time, it’s good to get rid of old habits and learn something new :), Chris, thanks for the article; as usual: perfect timing!

It does rely on a certain structure and can be quite tricky in a drop down because it is has its own positioning context. p:nth-child(1) or p:nth-child(0n+1) Represents every

that is the first element in a group of siblings. A slight tweak/safety check to that would be to check that the first argument passed through is actually a function: The list item could be buried three levels deep within other nested lists, and this selector will still match it. In your example you nested an OL, but change it to an UL (as you mention in the text) and the Nested Item 1 and 2 will also be targeted. If you need deeper support than that, the ie7-js project (now updated all the way to ie9.js) will get you support for all of this back to even IE 5.5 with a single simple JavaScript file inclusion. There is an in-depth course covering all of CSS, a Sass-specific course, a course on modern layouts, and a course on SMACSS, a approach to CSS architecture.

The list item selector is more specific, but it doesn’t select the OL or the OL LI’s, so the color remains black. This can be a challenge if multiple similar elements exist and/or similar elements exist at other elements within the … Powered by Discourse, best viewed with JavaScript enabled, Apply CSS style to parent only if there are child elements. IE 7 also has support, but be aware that HTML comments can screw them up and cause them to not match when in between siblings. What I am trying to do is add some sort of visual indicator to a li that contains child elements, in the case: On the previous code I cold just add some CSS properties to the id haschild however I want to know if there is a way to add the rules without the id, something like li:first-child but for parent, I already searched for that and I know it does not exist even in CSS3 but is there an alternative? Awesome article – these selectors always gave me trouble before, but it makes much more sense now. An adjacent sibling combinator selector allows you to select an element that is directly after another specific element. Important: For this example, as we are creating a child theme of Hestia Pro, we will name it hestia-pro-child. I’m assuming this thread is a continuation of tlacaelelrl’s previous thread so I have used the code from there to provide a rough example. They seem like they could be very useful! He just might be an alien from another planet. I get the example of the link: The child theme contains a "Template: parent-theme-dir" header to distinguish it from the standalone version. That provides an arrow made with css borders that is positioned into the top level list and turns into a down pointing arrow on hover. So if you are using a CSS ID it will work. This would be especially useful when you’re not sure what container the content will be in, but you need to add a style to that container.

  • Check out this interactive jQuery selector tester, with which you can test your expressions against your html. As you recommended ie7.project, a few questions popped into my head. A better example would be: . Adobe launched dreamweaver cs5 with a lot of features and one of them is css instection mode which will handle css properties. The amount of support is based on child support guidelines set by law. 3. Pretty amazing! Now that CSS ID needs to be unique or if you are using elements and classes, their combined selection needs to be unique. Thanks for the article Chris, it’s very informative. I was wondering, why there is adjacent sibling operator, and there is no nth-sibling selector? The adjacent sibling combinator (+) separates two selectors and matches the second element only if it immediately follows the first element, and both are children of the same parent element. This does not violate right to left rendering and memory issue, so Im rather curious if this was suggested before to the CSS draft and why it was rejected, and if it was not suggested, why not? And even talking about IE8, I’m not convinced it’s bad. If there are values that exist in the child theme stylesheet that do not exist in the parent stylesheet, they will be displayed as well. So like ul#main-navigation > li would only select those top level LI’s without selected other nested LI’s. Chris said: You would have to style the ol in order to get the nested li’s to change color (which is what Chris has done in the jsbin thing). the ol is black, so the bullet and the word “test” will be black. But I doubt anyone can see the difference between fast css and fast css(css is always fast). The hasChildNodes () method returns true if the specified node has any child nodes, otherwise false. no more ul li ul li ul li ul li {} !

IE 7 also has support, but be aware that HTML comments can screw them up and cause them to not match when in between siblings.”. I Cant believe that only now i came across that perfect post. Most of them start with

    elements and it looks great. Took me a while to using >, I’ll try to start to use + more, although I use some of the others with attribute selectors.

The second selector above is a child combinator selector. Or highlighting the first item in a list. They’re immensely useful and almost no one ever bothers with them. And the ie7-js project is very usefull too. What drastic effect these scripts could possibly cause to your website? Hi there. Yeah, even though the li’s in the ol are not targeted, they inherit the rules that the targeted li in the ul gets. Thanks for the tip. Why are people still afraid of using such scripts? JavaScript creations. I’ve said it many times before, but one of the major missing selector styles in CSS is some kind of “contains” (or “has” or “qualified” or whatever you want to call it.
