Using unicode characters to style your Angular application

Hey there! I have an Angular 5 app on StackBlitz that implements table sorting. You can check it out here: https://stackblitz.com/edit/angular-rxdzom. The code for this app is based on the example from . In the app, I've used a stylesheet at ./app/sortable-table/sortable-column.component.css with the following content:

.caret-up:before {
  content: "\f0d8";
}

.caret-down:before {
  content: "\f0d7";
}

The HTML file at ./app/sortable-table/sortable-column.component.html contains two i tags that reference these classes in the stylesheet. However, when I try to replace the caret symbols with Font Awesome icons ("fa fa-caret-up" and "fa fa-caret-down"), they display as rectangular boxes instead. Unfortunately, I cannot use Font Awesome in my work environment, so I'm trying to manually create the necessary CSS content. Any suggestions or assistance would be greatly appreciated!

I've done some research on my own and thought I had the correct solution, but it's not working as expected. I've referred to resources like which suggest that the CSS should be valid. I also attempted using ".caret-up i::before", but that didn't solve the issue either. I even experimented with adding:

padding-right: 10px;
font-family: "FontAwesome";

before the content property, but unfortunately, it did not provide the desired outcome.

Answer №1

It appears that the css code provided is located within your component's styles property. If this is the case, the problem lies in the backslashes not being escaped properly within the string. To resolve this issue, please update the codes as shown below:

.caret-up:before {
  content: "\\f0d8";
}

.caret-down:before {
  content: "\\f0d7";
}

Answer №2

If you're looking to enhance your designs with icons, consider utilizing material icons as an alternative option. You may access a wide range of icons by visiting the following link: https://material.io/icons/ Make sure to incorporate this link into your index.html file. In your CSS, don't forget to assign the 'material-icons' class to your desired property. For instance, you can use 'keyboard_arrow_up'. Feel free to explore and utilize various symbol names available on the provided material icons link.

Answer №3

Initially, I was unaware of the changes in our environment. We switched from font awesome to Semantic UI, which utilizes a modified version of the font awesome fonts. This meant that I had to adjust my code to accommodate these new fonts. To make the necessary changes manually, I simply needed to:

.caret-up:after {
padding-right: 10px;
font-family: Icons;
content: "\f0d8";
}

.caret-down:after {
padding-right: 10px;
font-family: Icons;
content: "\f0d7";
}

To ensure the icons appeared after the text, I had to rearrange the placement of the "ng-content" tag relative to the "i" tags for ascending and descending sort order. So, with the Semantic UI fonts, my sortable-column.component.html now looked like this:

<ng-content></ng-content>
<i class="caret up icon" *ngIf="sortDirection === 'asc'"></i>
<i class="caret down icon" *ngIf="sortDirection === 'desc'"></i>

The adjustments worked seamlessly. To demonstrate how I implemented these changes in my environment using Semantic UI 2.3.1 with the font awesome fonts, I created a fork of my Stackblitz app at https://stackblitz.com/edit/angular-nfwe6j.
