This feature would really help with designing with Webflow!

I wish we could style children of certain classes. For e.g. .main-navigation > li, rather than having to add a class on the li itself

Yes. I like to use CSS in the "object oriented" style decribed here. And it's just barely possible in webflow to define "Button .red .greenBorder" and later reuse the border like "Image .greenBorder" in a simple way (as far as I know). This would also allows for better maintainance since one can simply change .greenBorder and it changes it on the Button and Image the same way...

As a work around to the "A->B->D to A->C->D Problem" I make an empty throwaway-div with a "D" style, style it, and THEN add that "D" style to the elements. But that's a workflow that is needlessly complicated and prone to errors...

This ties in to a lot of other ideas here like editing Styles/Classes/CSS directly from the Style Manager or re-ordering the Styles in the Style Manager or simply to copy/duplicating styles a bit more easily.

I justed started using WebFlow having come from a hand-coding background and I'm in disbelief that this feature doesn't exist.

There is some really cool stuff in WebFlow, but the inability to style based on nested selectors is killing me. It may even end be a deal-breaker for me as the verbose HTML and CSS generated by having to give every single element a class or combination of classes is crazy.

I think the biggest issue with this problem is not being able to change class states once they are combo classed. I usually have to create a hidden version of the original class by itself. It's annoying.

Need this too! Please!

Yes please! 
It would be amazing if I could easily set up "global combo classes" and having control over them. For example If I have ".p .p--large .text--centered" I want to be able to use "text--centered" on all h1-h6.
 
I would use global combo classes for:
- Text Alignment
- Text Color
- Background Color
- Shadows
- Any other type of simple styling

This is a pretty major feature.

Even if we don't get the rest, at least allow us the ability to add pseudo classes first.

For all who are trying to figure out how to create a "global class" (as Webflow calls it) in webflow (class 'D' in the OP's example) you simply have to create an element with no classes (a fresh 'div') and the class you want, and style it the way you want (text-align: center) then you can delete that element and apply that class to any element that you want to have that style, whether it is a heading, p, button... with any other class!

You can store these primitive elements in a hidden page so that when you clean your styles, they don't get deleted if they're unused. 

As for pseudo classes, and nested class targeting (any .button inside of a .form - similar to how rich text fields work), those would definitely be helpful.

Please implement this ASAP!

Something I've been struggling with is styling elements according to whether the parent has a class or not.

A practical example of that would be a custom tab menu element: I want to change the size and color of each element inside the "tab-link".

• In CSS, what you can do is: add an "active" class to the parent element (.tab-link.active) and style children like this: .tab-link.active .child { ... }
• In Webflow, you have to use a workaround which is quite the hassle: use "active" classes to each element you want to make a change + use custom JavaScript to add/remove these classes for each individual element when a click is triggered.

Trying to use the excellent grid templet from Kevin Houle was a challenge because of how Webflow handles nested classes. I really like the idea of defining classes to control how many columns my divs should cover in this flexbox grid. Say I want a div to be 8 columns on desktop, 6 columns on tablet and 12 columns on mobile. I would logically assume that I could set up “global classes” for this (col-8, col-m-6 and col-xs-12) and use them independently of each other. But with Webflow's current combo class nesting, this is just messy. Btw, the template works, but the combo classes are not autocompleted as you type. You need to write it correct to apply the classes. And as you know it will result in a combo class tree structure for every variation of layout you set up. Not very clean and reusable, I’m looking at you Webflow ;-)

Bump. Could use this!

Can't believe this isn't implemented yet. It's such a basic concept. They even have a nested selector for rich text!

This was the one big disappointment for me as a new Webflow user and as someone who has used utility based CSS frameworks like Tachyons before. 

I'm sure you see this a lot but I've created a system of global styles by creating temporary elements, applying styles, then removing the element. Its frustrating having to do this every time I need to create a style that is used elsewhere.

Copying my post from the forum to this wish to add my vote (link to original post).

Coming from the design space (Sketch and Figma) I’m used to thinking design implementation in terms of style guides. That means approaching design modular with reusable parts. I would typically define spacing sizes, background colors, border colors, border widths, drop shadows, etc. I use these styles and symbols in different combinations to create components and templates (the atomic design principles).

Moving to Webflow I would expect the possibility to transfer the same logic and use global classes that represent my styles/atoms and use the global classes in different combinations to create the design I want. But Webflow seems to be against this type of organization. I read in the forum that you don’t “believe” in combining global classes. You think that it’s dangerous to have one class affect multiple elements in the design :exploding_head: You instead implemented the concept of combo classes. Combo classes, I can tell you, is not a good way to work for people that are used to work in Sketch/Figma with styles/atoms. This is absolutely not good design system practice.

I hope that you decide to support combining global classes for us design system people. It’s a must-have. I don’t want you to remove the combo class pattern, just extend and improve it. I should be able to decide when to use a combo class or a shared global class. I know I can hack it today, which is a terrible pattern, and that is what I want you to fix – make right.

I like the combo class concept, but like mentioned already, there are many times where I want to add a stand-alone class to an element without it being a part of a combo class. 

Maybe a more straight-forward solution would be to simply have two selector input boxes, one for standalone classes and one for combo classes.
