问题 I have an Angular 5 app that must use Angular Material's mat-select inside a Bootstrap modal. The issue is that the dropdown options appear behind the modal. My code looks like this: <mat-form-field class="mdb-form-field form-adjustments"> <mat-select placeholder="What fruit are you looking for?" [formControl]="fruitType" [(ngModel)]="defaultFruitType"> <mat-option *ngFor="let fruitType of fruitTypes" [value]="fruitType">{{ fruitType }} </mat-option> </mat-select> </mat-form-field> I know I

问题 Given this markup: <div class="parent" data-active="typeA"> <div class="child" data-show="typeA">Show only when parent=typeA</div> <div class="child" data-show="typeB">Show only when parent=typeB</div> <div class="child" data-show="typeC">Show only when parent=typeC</div> </div> I'm trying to write a globally applicable LESS rule that only displays a child when its data-show attribute matches the parent's data-active attribute. Something like this: .parent { .child { display:none; } &[data

If you

问题 How can I allow users to change web page -built with bootstrap- font size when clicking on a button? I would like to change all components font size relatively. Is this possible? Thanks, 回答1: This is usually done with Javascript and cookies. Here's an example using jQuery: Quick and Easy jQuery Font Resizer Tutorial 回答2: Bootstrap uses global @baseFontSize parameter that controls font size of all elements, but changing it would require re-compilation of the css with less. 来源： https:/

问题 So I have setup my site to use modules, in which each module has it's own .less file which needs to be compiled into .css. Folder Structure: /common/modules/{module-name}/style.less I need all the style.less files to be converted into style.css files in the same directory. For example: /common/modules/clock/style.less would need to be compiled to /common/modules/clock/style.css I don't want to have to add each of the modules individually to my grunt file, is there a way to do this dynamically

问题 I need to override some global variables used within a mixin. However I'm reluctant to just change the variables in global space (wouldn't be overriding then) Consider this given mixin with the required variable defined. // Mixin and adjust the regular image class .thumbnail { display: block; padding: @thumbnail-padding; margin-bottom: @line-height-computed; line-height: @line-height-base; background-color: @thumbnail-bg; border: 1px solid @thumbnail-border; border-radius: @thumbnail-border

问题 Suppose I've parsed my mixin parameters and colours are provided using rgba function. Now I would like to mix two of those colours, but LESS mix function requires parameter instances of type color . What I tried ...and doesn't work calling color("rgba(0,0,0,.5)") mix(@first, ~"@{second}") where @second is a string like rgba(0,0,0,0.5) How do I convert to color? 回答1: I'm afraid you won't find a built in function to do this in LESS. The color() functions argument needs to be a hexadecimal or
