Why can't I change the width of html buttons on class level in css? [duplicate]

-
5

I want three buttons to each take up 33% of the assigned space. They are grouped in a class "numbers".

When I define the width for the button tags, that works fine, but when I do it for all buttons in the class that they belong to, nothing happens.

html:

<html>
<link rel="stylesheet" href="opmaak.css">
<body>
    <section class="numbers">
        <button type="button" value=1> 1</button>
        <button type="button" value=2> 2</button>
        <button type="button" value=3> 3</button><br>
    </section>
</body>
</html>

css when I do it on button level:

button {
    width: 33%;
}

css when I try it for all buttons of that class:

button.numbers {
    width:33%;
}

Could anyone point out why that is?

button.numbers {
    width: 33%;
}
<html>
<link rel="stylesheet" href="opmaak.css">
<body>
    <section class="numbers">
        <button type="button" value=1> 1</button>
        <button type="button" value=2> 2</button>
        <button type="button" value=3> 3</button><br>
    </section>
</body>
</html>

  • .numbers button {...}, also it would be good to put your <link... tag into a <head> section – biesior Apr 3 at 10:13

Meaning of `{}` for return expression

-
15 1 I found by accident that the following compiles: #include <string> #include <iostream> class A{ int i{}; std::string s{}; public: A(int _i, const std::string& _s) : i(_i), s(_s) { puts("Called A(int, const std::string)"); } }; A foo(int k, const char* cstr){ return {k, cstr}; // (*) } int main(){ auto a = foo(10, "Hi!"); return 0; } The line of interest is (*). I guess the function foo is equivalent to: A foo(int k, const char* str){ return A(k, cstr); } However, is there a special name for this mechanism in (*)? Or is it just the simple fact that the compiler knows which constructor to call due to the return type? ...

Get current scroll position of ScrollView in React Native

-
Is it possible to get the current scroll position, or the current page of a <ScrollView> component in React Native? So something like: <ScrollView horizontal={true} pagingEnabled={true} onScrollAnimationEnd={() => { // get this scrollview's current page or x/y scroll position }}> this.state.data.map(function(e, i) { <ImageCt key={i}></ImageCt> }) </ScrollView> Try. <ScrollView onScroll={this.handleScroll} /> And then: handleScroll: function(event: Object) { console.log(event.nativeEvent.contentOffset.y); }, Disclaimer: what follows is primarily the result of my own experimentation in React Native 0.50. The ScrollView documentation is currently missing a lot of the information covered below; for instance onScrollEndDrag is completely undocumented. Since everything here relies upon undocumented behaviour, I can unfortunately make no promises that this information will remain correct a ...
