I'm developing a small control which is directly embedded in a parent page (without iFrame).
My control is written using react-bootstrap, so the bootstrap4 css is also embedded along with my control.
While developing my app as standalone, everything was fine.
After embedding it however, it turns out that there are some "global" bootstrap styles, such as the so called "list-styles" that don't get applied only on HTML elements having bootstrap classes, but instead on any matching HTML tag.
This causes the parent page's layout to get scrambled once my control is loaded.
Examples for bootstrap classes that are applied globally and which cause problems for me are styles like these which can be found in the bootstrap4 default css:
dl, ol, ul {
margin-top: 0;
margin-bottom: 1rem;
}
or
label {
display: inline-block;
margin-bottom: .5rem;
}
This is very unfortunate for my use case. Is there a way for getting rid of any styles in bootstrap, which are not linked to any proper css bootstrap class? I don't want any styling of HTML tags that are not explicitly linked to a bootstrap class.
Thanks for your help.
I can think of three options, though I'm not sure they will do for you:
Paste Bootstrap's styles into a local file (instead of getting them from a CDN or something) and delete what you don't want (most of the unwanted styles should be at the top of the file)
Look for another, more minimal version of Bootstrap. I don't know if such versions/customizations exist but they very well might
Don't use Bootstrap. You can just as easily write your own css lines (personally I find that Bootstrap makes you lose control over your styling, but that's my opinion)

I'm trying to change the padding on mat-cell and I've noticed some weird behavior.
If I write the css inside the component's css file everything works just fine, but if I write it in style.css (I want to apply it to the whole app) it gets overwritten by the default.
I guess this has to do with the order in which the css files are applied. If that is the case, how can I see this order and is there a way to change it or bring style.css on top?
I would suggest to create a separate .scss file reserved for styling globaly Angular Material elements, and importing it in the main styles.scss file.
Answering your question - propably you're not 'specific' enough. First of all it would be nice to add an additional custom class to your Material element so the custom styles will be applied only when this class is present. Example on styling
.mat-table.my-custom-class {
width: 100%;
.mat-cell {
font-size: 20px;
padding: 20px;
}
}
You might nest the elements event more for higher css specificity
That works for me:
.mat-cell {
padding: 12px!important;
}
Check for the parent scope of default style which is overriding css added in style.css using developer tool. Use the same parental scope along with !important.
I'm working on a new web app and I'd like to create my GUI mockups in Illustrator then implement them in HTML5 and CSS3 using Twitter Bootstrap. I know how to use the CSS classes to create my pages but I'd like to know the process of customizing Twitter Bootstrap to match my mockups as much as possible. I'm talking about colors, typography, margins, padding, borders, button styles and so on. I'd like to create completely different themes for this and every future project I'll be working on.
I'm a programmer but I love GUI design too so I'd like to know how professional designers make all the pieces fit in.
Thanks in advance.
In order to get the most out of Bootstrap (especially the new "mobile first" features) I recommend using your Illustrator file as a jumping off point, rather than a spec.
I agree with the other commenter who suggested leaving the Bootstrap file in place and writing a second file with selective overrides. This is much easier with Bootstrap 3 since the flat design means less to clobber with your own declarations.
I always start with laying out a static version of the pages using plain Bootstrap then methodically cherry picking styles using the inspector (e.g. body backgrounds, typography, colors) in priority order as they stand out to me visually. I usually wind up with something that is close, but slightly different (often better), than the original design.
Good luck! If you don't fight it too hard, Bootstrap offers a lot out of the box.
I'm pretty new to Bootstrap but the general consensus seems to be to leave the actual Bootstrap.css intact and create different CSS files to override Bootstrap. For example in this snippet (SCSS by the way) I commented a section as "General" and placed some default overrides for my site. Most notably would be the restyled input boxes from rounded to square.
/********
GENERAL
*********/
html, body {
height: 100%;
}
.wrap {
position: relative;
overflow: hidden;
min-height: 100%;
}
body {
a {
color: #FF4329;
&:hover {
text-decoration: none;
}
}
input[type="text"], .btn {
-webkit-border-radius: 0;
-moz-border-radius: 0;
border-radius: 0;
}
}
Also note that you can customize the files you download from Bootstrap so if you plan on using on the the grid system then that's all you need to download.
If you're planning to use the grid system of Bootstrap, there're plugins for Photoshop and Illustrator that create guidelines for you (you can even specify the padding, number of columns and margin).
Bootstrap is based on CSS. When you design something in Illustrator, you'll have to export assets like images but it's important to make use of CSS also for the most things you can. Remember, it's faster to apply a CSS background-color instead of using an image for that purpose as background-image.
I make my scratches on paper and pass right away to html. With chrome developer tools you can easily change the css styles applied, apply new rules, etc
I am using twitter bootstrap for layout and css. But I like the foundation top bar navigation over what bootstrap provides. I tried to use the top bar code inside my html (built with bootstrap) and it messes up the layout. That is not surprising because both of them rely extensively on class named "row" and they have different properties.
One of the options I could think off is to override the row class some how in my style sheet but that would be too much of a work and doesn't seem right.
Other option might be using iframe.
Is there any other way this issue can be solved?
Ideally, you only need to use the top-bar CSS and JS code of Foundation, since that is the only component you mean to use. Here is the SCSS file (with dependancies on the variables declared in _settings.scss. Or you can use the generated CSS code.
If you still need to use .row, just copy the .row styling and name it different. I.e:
/* The Grid ---------------------- */
.foundation-row { width: 1000px; max-width: 100%; min-width: 768px; margin: 0 auto; }
Finally, dont't forget to include the jquery.foundation.topbar.js file and calling
$(document).foundationTopBar();
Old question but thought I'll share the latest if someone is looking for a seamless solution: Web Components
It's a bit of a more complex subject but will allow you to create widgets within completely isolated Shadow DOM's without overriding a thing. Read more about it
here and here. Then you'll be able to do something like this:
<template id="templateContent">
<style> #import "css/generalStyle.css"; </style>
</template>
Taken from this answer
Using an iframe for this is a bad idea. If you like the style for the Foundation top bar, just copy those styles into a custom class in your stylesheet.
Please note that you may have to override some of Bootstrap's default styles for the top bar to get it right.
I just started to port twitter's bootstrap to GWT (see the github project here and a very ugly demo here), but, I was having a log of issues with bootstrap styles vs Gwt styles.
Bootstrap put a border-top in tr/td elements, and GWT components basically use tables everywhere. In the demo you can see that bug in the left VerticalPanel.
So, I was looking for a way to make GWT components ignore bootstrap styles, and I have no idea how to do this.
Is there a simple way to make it work right?
Thanks in advance.
It's possible, but somewhat complex to do something with a Linker in GWT. The high-level idea would be:
Put all your GWT components in a <div id="gwt">...</div>
Add a linker to the GWT Module file that will process CSS files.
In the linker, transform the GWT CSS (e.g., standard.css) to insert a #gwt before each selector rule.
The first part is easy, just add an id to your root element.
The second part is also easy, simply add code that looks like this to your Module.gwt.xml file:
<define-linker name="cssLinker" class="com.you.bootstrap.linker.CssRenamingLinker" />
<add-linker name="cssLinker"/>
The hard part is implementing the Linker. It's possible to do parse it by hand, but you might find it easier to use something like SAC.
Using the Linker, you can transform your CSS by inserting a #gwt before each selector. Using SAC, you might do that by overriding all the DocumentHandler methods to simply emit each of their arguments to an OutputStream. In DocumentHandler.startSelector() you would first emit "#gwt " before each selector.
[Edit]
This assumes that GWT's standard.css defines styles that override the bootstrap styles. If not, you might have to 'enhance' the GWT CSS with defaults. There's a list of W3C recommended defaults here.
The benefit is that this is future-resistant - if GWT styles change or if bootstrap styles change, this should be robust.
Hope that helps,
Adam
You can simply add a style to one of your root GWT objects and then simply override the bootstrap styles to remove those messy borders:
<div class="gwt">
... some other GWT-content
</div>
and in your CSS:
.gwt tr, .gwt td {
border-top: 0px;
}
Of course if you need to embed some bootstrap elements in your GWT elements then you will have to hack around and do:
<div class="gwt">
... some other GWT-content
<div class="bootstrap">...
... Bootstrap elements
</div>
</div>
and in your CSS:
.bootstrap tr, .bootstrap td {
border-top: 1px; // Whatever bootstrap style puts
}
I am building a jQuery UI site. I can see how easy it is to add widgets or dialogs and also I have seen it is possible to style elements using the theming api:
http://jqueryui.com/docs/Theming/API
So how do I style things like normal text or html headers 1-3 or html tables?
I would like to use the classes and styles from jQuery UI so everything fits together and changes when I change the theme.
I have tried to apply ui-widget-content or ui-widget-header to divs or h1,h2, but maybe there is a better way, or an in depth tutorial somewhere.
I usually detect the class of the theme I want to customize, and then instead of changing directly in the jquery css, (because I prefer to have udner control my changes, and ebcuase if I update the theme, don't need to add the changes again) , I add these modified classes in an "override" block or how you want to name it, so that are same classes, but with an important;! or other hierarchy trick added. For instance, calling the parent ID to give it more weight: #content .ui-widget-content {whatever} , or .ui-widget-content {whatever property:whatever value !important;}
Is usually some small bits, never a large portion of things that I want to customize, so adding these 2 or 3 classes in my main.css does not hurt. It depends, though.
edit: Oh... with "oder" you meant "order". Sorry, was not understanding well your question (is a bit unclear).
If you are not supporting IE7, you might be interested in using:
tr:nth-child(even) {background: #fff}
tr:nth-child(odd) {background: #000}
