css if child exists

ul { color: red; } I added the id as an example just to be as clear as possible on what I am trying to do. Replace the first selector with the child you are testing and the second selector with the parent you are testing for. That sounds like gibberish kind of… Here is an example where the inner OL has a color of black, then the parent list items have a color of red. Here’s the way we can do that. But some of them start with a

, which have top and bottom margin on your site to look good within an article. Maybe you want to make the outer-most list items large and header-like, but the nested lists smaller and more body-copy like. If we use the same example structure as above, the last

element will be selected by p ~ p as well, because it is preceded by another

element, even though not directly. Apparently the powers that be have rejected it a number of times for some complicated reasons (speed related, I think). If you take the ol out of the 2nd li (with content List Item Two) then indeed only the 3 main li’s will be red, but only because the nested li’s are children of a ol. Thanks! However the ol is enclosed by li tags so the entire ol becomes an li which is the child of the ul and with the style ul>li color red the ol will be red which means the bullet is red. I should clarify in case there’s some doubt that :before does not mean before the element concerned. I knew about >, and use it regularly, but I’ve never heard of + and ~. But if you were to us a within a and use ul>li this will surely still style the inner ul li’s? We recommend you name the child theme folder this way for Hestia PRO and hestia-child for Hestia, to be sure, you can migrate the options from the child theme to the parent theme if you want to switch back at some point in time. a decision I'm very happy with. Because :has() is a jQuery extension and not part of the CSS specification, queries using :has() cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. They are cool selectors and especially useful for styling menu’s. The child combinator (>) is placed between two CSS selectors.It matches only those elements matched by the second selector that are the direct children of elements matched by the first. But no, you can’t style a parent on the basis of a child in CSS. (Hope they’ll let you trade your MBP. That’s what siblings means… sharing the same parent. We’re going to discuss few methods. jQuery can do it: And can even be adjusted to use the “jQuery.parse.push(/^\s*(<)(\s*)(. if ($ (".child-element").parents ("#main-nav").length == 1) { // YES, the child element is inside the parent } else { // NO, it is not inside } Need some front-end development training? Let’s drive that same example home with a visual: I think the nested list is a perfect example of why this selector is useful. It would be something like this (or I would like to hear suggestion): Where just using p:nth-sibling(2) would select every second p that comes after any element. This would be the same as :first-child:last-child or :nth-child(1):nth-last-child(1), but with a lower specificity. “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.”. The idea being like “select all paragraphs that contain images”. img + p { font-weight: bold; } The :only-child pseudo-class selector property in CSS represents an element that has a parent element and whose parent element has no other element children.

The above would add the word test before any content in the paragraph. IE8 was a css catch-up session, their attempt to fully support CSS2, and almost passes acid2. I queried the forum and was provided the code to add to my function.php file in the child directory. In the graphical examples above, that’s what the wrapping

is there for. What is proposed though, in the upcoming CSS Level 4 Selectors specification (aka “not CSS4” 😜), is an extension to the nth-child/nth-last-child pseudo selectors: the ability to add an extra "of S" part into those selectors. This comment thread is closed. When a browser parses css selectors, it can apply the styles to each element by iterating through each element exactly once. 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! But there is a difference between children and descendants. 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.

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 really wish there was a “parent” selector. That's a good thing! So if there was another unordered list nested deeper, the list item children of it will not be targeted by this selector. is used before selector to … In your example the ol is enclosed by the li tags from List Item 2, as a result the whole ol will be styled in the same fashion as the ul>li. These will be very useful going forward. In my opinion, IE6’s single greatest sin is not having support for these selectors. Because they are making code easier to read (both css and html). 6. display. The :only-child selector matches every element that is the only child of its parent. I've used WordPress since day one all the way up to v17, I recently created a child theme so I could make changes in the function.php file. Hi Chris, I am making a menu using an ul, however I want to be able to reuse the CSS. This article really help us. I just tested this.

For example lets consider this situation: So what if you want to select only middle p but only after the div.only-after-me (this is currently impossible as I know)? The latter selector above would zero out that top margin when it begins an article (immediately succeeds a title).

. Adobe launched dreamweaver cs5 with a lot of features and one of them is css instection mode which will handle css properties.

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.
