Introduction to the use of several special attribute tags in HTML

The following attributes are not very compatible with browsers.

1.transform:rotate(45deg)
2.border-top-left-radius This property allows you to add rounded borders to an element
3.border-radius This property allows you to add rounded borders to an element
4. The box-shadow property adds one or more shadows to a box
5. The text-shadow property sets a shadow on the text
6. Transition

In order to better compatibility with various browsers, a prefix is required.
-o- /*Opera browser*/
-webkit- /*Webkit-based browsers Safari and Chrome*/
-ms- /*IE 9*/
-moz- /*Firefox browser*/

1.transform:rotate(45deg)
Use the transform property to rotate the object, where (45deg) is the angle of rotation

transform:rotate(45deg);
-ms-transform:rotate(45deg); /*IE 9*/
-o-transform:rotate(45deg); /*Opera browser*/
-webkit-transform:rotate(45deg); /*Webkit-based browsers Safari and Chrome*/
-moz-transform:rotate(45deg); /*Firefox browser*/

2.border-top-left-radius border-radius This property allows you to add rounded borders to an element <br />The former allows you to choose where to add the rounded border
border-top-left-radius,border-top-right-radius,border-bottom-left-radius,border-bottom-right-radius
border-top-left-radius This property allows you to add rounded borders to an element. It is the same as border-radius, but you can control where the rounded border needs to be added.

3. The box-shadow property adds one or more shadows to the box, and the text-shadow property sets a shadow to the text
box-shadow: h-shadow || v-shadow || blur || spread || color || inset;
Properties: horizontal shadow position|| vertical shadow position|| blur distance|| shadow size|| shadow color|| change outer shadow (outset) to inner shadow
box-shadow:1px 1px 3px #292929;

text-shadow: h-shadow || v-shadow || blur || color;
text-shadow: 0px -1px 0px #000;

4. Transition
property || duration || timing-function || delay
Specifies the name of the CSS property that sets the transition effect|| Specifies the number of seconds or milliseconds that the transition effect takes to complete|| Specifies the speed curve of the speed effect|| Defines when the transition effect starts

The transition property is not currently supported by all browsers.
ease The default. The animation starts slow, then speeds up, then slows down before ending.
ease-in The animation starts at a slow speed.
ease-out animation ends at a slow speed
ease-in-out animation starts and ends at a slow speed

transition:background 5s ease;
