I'm writing a website in HTML5 and Bootstrap 4 and I'm trying to turn a square image into a circle. In Bootstrap 3 this was easily do-able with .img-circle, but now I can't seem to get it to work and I can't find any answers online. Has Bootstrap dropped the img-circle class or is my code messed up?
It goes something like this:
<!-- Within a tab-content div --><divclass="col-xs-7"><imgsrc="img/gallery2.JPG"class="img-circle"alt="HelPic></div>
Use the .shadow-inner utility to apply a subtle inset box shadow to an element. This can be useful for things like form controls or wells.
.shadow-inner
<divclass="shadow-inner"></div>
No shadow
Use .shadow-none to remove an existing box shadow from an element. This is most commonly used to remove a shadow that was applied at a smaller breakpoint.
.shadow-none
<divclass="shadow-none"></div>
Responsive
To control the shadow of an element at a specific breakpoint, add a {screen}: prefix to any existing shadow utility. For example, use md:shadow-lg to apply the shadow-lg utility at only medium screen sizes and above.
For more information about Tailwind's responsive design features, check out the Responsive Designdocumentation.
By default Tailwind provides three drop shadow utilities, one inner shadow utility, and a utility for removing existing shadows. You can change, add, or remove these by editing the shadows section of your Tailwind config.
If a default shadow is provided, it will be used for the non-suffixed .shadow utility. Any other keys will be used as suffixes, for example the key '2' will create a corresponding .shadow-2 utility.
By default, only responsive variants are generated for shadow utilities.
You can control which variants are generated for the shadow utilities by modifying the shadowsproperty in the modules section of your Tailwind config file.
For example, this config will also generate hover and focus variants:
{
// ...
modules: {
// ...
- shadows: ['responsive'],
+ shadows: ['responsive', 'hover', 'focus'],
}
}
Disabling
If you don't plan to use the shadow utilities in your project, you can disable them entirely by setting the shadows property to false in the modules section of your config file:
Assign responsive-friendly margin or padding values to an element or a subset of its sides with shorthand classes. Includes support for individual properties, all properties, and vertical and horizontal properties. Classes are built from a default Sass map ranging from .25rem to 3rem.
Notation
Spacing utilities that apply to all breakpoints, from xs to xl, have no breakpoint abbreviation in them. This is because those classes are applied from min-width: 0 and up, and thus are not bound by a media query. The remaining breakpoints, however, do include a breakpoint abbreviation.
The classes are named using the format {property}{sides}-{size} for xs and {property}{sides}-{breakpoint}-{size} for sm, md, lg, and xl.
Where property is one of:
m - for classes that set margin
p - for classes that set padding
Where sides is one of:
t - for classes that set margin-top or padding-top
b - for classes that set margin-bottom or padding-bottom
l - for classes that set margin-left or padding-left
r - for classes that set margin-right or padding-right
x - for classes that set both *-left and *-right
y - for classes that set both *-top and *-bottom
blank - for classes that set a margin or padding on all 4 sides of the element
Where size is one of:
0 - for classes that eliminate the margin or padding by setting it to 0
1 - (by default) for classes that set the margin or padding to $spacer * .25
2 - (by default) for classes that set the margin or padding to $spacer * .5
3 - (by default) for classes that set the margin or padding to $spacer
4 - (by default) for classes that set the margin or padding to $spacer * 1.5
5 - (by default) for classes that set the margin or padding to $spacer * 3
auto - for classes that set the margin to auto
(You can add more sizes by adding entries to the $spacers Sass map variable.)
Examples
Here are some representative examples of these classes:
Additionally, Bootstrap also includes an .mx-auto class for horizontally centering fixed-width block level content—that is, content that has display: block and a width set—by setting the horizontal margins to auto.
Centered element
<divclass="mx-auto"style="width: 200px;">
Centered element
</div>
